Tech Help / Re: Changing patches using the Zendrum's buttons?
« on: November 10, 2010, 08:29:33 am »
DrumWagon,
Thanks for clearing that up for me.  'Tis a shame about the two stage patchchange since it introduces more of a delay which potentially could inhibit my clave solo coming in on time ;D
At the moment I am using the midi channel to control seperate vitual instruments but long term I want to get to the point whereby I can change instruments via programme change messages alone in my DAW host (Sonar 8.5).  i just haven't got the midi expertise to work out how to do this yet i.e send a programme change message with each change on the LT that solos a given channel containing the target vsti whilst muting all other channels.  I know it is possible with Cubase because I have seen a chap called Tony Ostinato do it with his EWI wind controller on Youtube (I also have an EWi that I play alongside the Zen).  Must get a midi basics lesson, methinks.

Thanks again for your help.

Dave

Tech Help / Changing patches using the Zendrum's buttons?
« on: November 08, 2010, 05:44:24 pm »
Hi fellow drummers,
I have an LT upgraded to z4 and use it to run Superior 2.0 and other vsti's.  I am currently setting it up so that programme 1 outputs on midi channel 10 which triggers the SD2 vsti and programme 5 outputs to Yellow Tool's Inedpendence pro running "Culture" on channel 11.  The idea is to have both instruments ready for action in any given song (drums from SD2 and percussion from Culture) and they both work fine except that the programme up and down buttons do not initiate the new patch as soon as I scroll to the respective programme number.  I need to add an additional press of either the left arrow or right arrow button after scrolling to the appropriate number to start the respective vstii.  Is this normal behaviour?  Should I expect the vst's to automatically be addressed as I scroll up or down?
Also, I don't notice a huge difference in sensitivity between the old pcb and the new one - maybe I don't play subtly enough yet though.  I have adjusted the parameters for sensitivity, noise floor and gain etc but await any suggestions from the forum.
Finally, last night I noticed that a tiny LED light flashes (x1 to x2 per second) next to the main display at a regular interval even if I am not triggering anything by playing.  Any idea if this means anything that I should be aware of?  Again, is this normal?
Thanks in advance for any light shed on this?  Thanks.

Camco - will have to take some pics on Sunday (+ I am due to play my Zendrum then too - now that it is upgraded to Z4 spec!  Need to get my DAW laptop back from repairs to set it all up ready for the weekend).
My plans for the column speaker were all done on paper with a pencil I am afraid.  Effectively, I sourced the speakers, modelled them in the free software to give me dimensions for a box (inc a port) and then played with the dimensions to give me an aesthetic end result.  this took ages to finalise though, because there were always compromises to make based on the driver dimensions, the need to protect them from over-excursion (and therefore damage), the thickness of the MDF I used as the structure for the box, fittings etc.  In the end the box turned out to be a few mm's wider than the combined width of the driver itself + the width of the MDF.  Depth was the one dimension that I could play with to alter the volume to match the recommended, modelled specs.  It is important to get the speakers as close to each other as physically possible to reduce comb-filtering as much as you can.  And of course, make the box airtight except for the ports.  Cutting 32 holes was very tedious!!
Wiring the 16 speakers in each column followed a series-parallel configuration to give me a combined resistance of 2 ohm (you can find examples on google) but you could wire them differently (ie series) to give you an 8ohm load which opens up more options with cheap amps.  I would probably do this next time too because cheap amps that are happy at 2 ohms AND have reasonably low W outputs are rare (and most are expensive).
The plans for the sub can be bought from Bill Fitzmaurice and are very thorough.  It gives you all the information you need to build one and the forums provide exceptional support.
As an aside, there is a guy (John Murphy) on the Parts Express Project Forum who has published detailed plans of an extended line array set-up (the MCLA) that may take some of the learning curve out of a design.  it looks very interesting and I am following it with interest.

Sorry if this is taking it off topic from the OP (please berate me if it is).
I did a lot of research into Line Array theory and speaker building prior to starting the project.  We had the use of a L1 mkii for a weekend at our church (gymnasium with wood floors/ block walls/ metal ceiling - an acoustical nightmare which meant speech and song with a "conventional" mid/hi system was a nightmare esp when adding in monitors) and the difference in clarity and intelligibility was tangible.  Unfortunately Bose was too expensive (over 2.5k  euro) so I thought that I would build one!  I used 32 tangband drivers 2" Mid/Fullrang W2-852SE/SF/SG (16 in each section wired to 4ohms  for each section which, when connected together, gave me a seven foot column of 32 speakers at 2ohms capable of handling 32 X 15 watts = 330w.  Efficiency of the line array physics of combined drivers means that I have never needed to drive the column anywhere near it's max - even on one outdoor gig where I covered 250 people with it (presentations, ambiance music and then backing music for Irish dancers).  Used a diy built T18 as the sub (20" squared box -horn sub with an 8" speaker from Bill Fitzmaurice designs) which is run with less than 50 watts of input and easily covers the bass end of things in a room approx 25 yards square.  They are very efficient designs but you can buy plans for greater power output subs at the same site should you need it.
Both builds took a bit of work.  Line array took a month or so of evenings to research, model various candidate speakers, design the column with ISD free speaker software, source materials etc.  Sub took a couple of days to build and is easily in the scope of most people with a bit of handy skills and a few tools.
I run a DBX PA system to control crossover, limiting, feedback suppression and eq duties to the rig.  Had to attenuate down the column speakers sooo much to keep them balanced with the sub.  Adding an additional sub would open up bigger audiences.
Shortcomings would probably be in the mid bass frequency - I crossover at around 120 which is high, but this is a protective measure.  The xmax for the drivers is 2mm and I am being overly careful to prevent this happening BUT I never drive them anywhere near to this so I could probably tune the column / sub a little better.
Comparing what I have to the L1 - if money is no object the L1 is such a compact solution that it is hard not to recommend (so long as you accept the compromises that using smaller speakers in a line array bring).   I couldn't bring myself (nor the churches equipment budget) to that level.. i estimate cost of column was about 400 euro all in (inc hardware, special speaker paint, custom metal grill etc) and the sub was 160 euro (most expensive part was shipping the 25 dollar driver from the States which ended up costing 65 euro!).  Secondhand DBX PA and a new Mackie rack amp were an additional 500 euro so I got a system for just under 1200 euro.  Factor in the time it took and then it doesn't look quite so rosy - it did become a bit of an obsession getting it done. 
BUT I get nothing but compliments about the sound - great evenness throughout the venue, speech is FANTASTIC, we put all the musicians through it (ac guitars, drums, vocals, synths, bass, bodhrans etc), AV presentations sound great and it ...just.. works for this very specific application.  Have use it in a coffee house environment with and without the sub and again, it works great for our purposes.  It is so portable and easy to set up.  3-4 mins and we are good to go.  No monitors needed - the spread of the output allows our musicians to hear direct from the speakers (we used to have lots of difficulty with our musicians getting a reasonable monitor mix with our convention FOH / wedges.   The paradigm shift to Line Array took a little getting used to but our main musician never bothers wearing his in ear headphones for monitoring any more - says it all).
If I were to start the task again - I would consider larger drivers with a great xmax and a lower Fs so that mid bass / bass in the column would be more even and I could possibly dispense with the sub for some gigs (ie no huge kick and bass needs).
Hope this helps and ....sorry again if this took us far off topic.

Housed in a Studio2go 4u rolling rack which incorporates a home made 2.1 monitoring system for practices in very small venues (adapted from a Logitec Home 2.1 system but sub re-modelled to hit into 2u space in rack).

Outputting into a custom built tall line array (a la Bose L1) with a Bill Fitzmaurice designed T18 sub for church/ coffee shop/ open air PA duties.

ZenChat / Re: On the topic of Zendrum sounds
« on: April 14, 2010, 10:47:59 am »
Both very interesting propositions, Inspector109 ( the caveat with the first option is to have a sufficiently sampled  kit to rival existing sound modules, eg rack mounted versions of Korg, Yamaha and Roland synths that have reasonable drum collections in them / on add-in cards.  A half rack mount module still remains a reasonably portable alternative to a merge brick module thingumyjig).  As ever though, much would rest on price points etc.
You like breaking things and I like fixing broken things.......will you marry me!!!!  Err, sorry Gina, got carried away :D

Hi Inspector 109, were you thinking along the lines of the Receptor or something totally different? I think that many of us have invested in proprietary sound libraries and would love a module that could eliminate taking the laptop, interface and attached sundries out and about with us whilst allowing us access to our favourite kits.  I recognise it is often a case of what is to be compromised ( for example, I used to play my custom vdrums with a Roland TD-8 module upgraded with a couple of v-expression vex packs.  It was easily better than my laptop system with all of it's sample libraries in terms of portability, kit piece tweaking with hardware faders, kit change speed, headphone monitoring to a click etc BUT the sounds didn't compare to software vsti's).  At the time, I played EZdrummer and Battery and always felt that the TD-8 sounds were a poor substitute but i could transport my zendrum (or Trapkat) and the td-8 so readily and conveniently to practices etc.
I eventually sold the TD-8 to fund other things but still occasionally hanker after it's convenience.   My laptop system is as compact as I can get it now (all encased in a SKB studio to Go unit) and it is reasonably portable but IF your proposed system was open-ended in terms of what sounds could be loaded then it would make for a VERY interesting proposition.  With decent kits coming under 1-2 gigs in size, I could see usb drive kit changes or SSD storage as real space savers.  I would be prepared to forego vast tweakability in order to get a rock-solid, high quality sample player that I could either chuck into a gig bag or a 1u / 1/2u rack space that would boot quickly and allow me to get up and running.
Interesting developments in Zendrum land in any case.  Look forward to more posts about it.

Thanks Gina,
Next time I will probably hire a car to ive me more mobility.  Will give you a shout if a trip is looming (maybe I'll bring in my LT for a tune-up!).

So, my first trip to the States took place over the last week and where should I be staying?  Duluth in Atlanta! A mere stones throw(considering I travelled from Dublin in Ireland) from the HQ. 
I had hoped to get some free time to be able to contact the main man and arrange a visit to see the "hatchery" where ZD's are created but it just wasn't happening on this trip.  Maybe the first of many trips though so you never know.
America was a blast!  Can't wait to come back some day and experience more of that warm Southern hospitality!

Tech Help / Re: Merge box polarity angst
« on: September 12, 2009, 09:13:37 am »
I bought an LT off of Ebay a year or so ago complete with US adapter plug.  Bought one of the Maplins tiny US to UK transformer plugs and all was well - then decided to rationalise things a little by locating a suitable specced UK 3 pin adapter and then replacing the US one with the UK one.  It needed an email to David to confirm the polarity of the cabling into the black plastic box (VERY important) but once that was clarified it was just a case of stripping 4 wires, matching up the polarity and then soldering +heatshrinking the joins and an additional heat shrink over the whole lot.  Works fine and don't have to lug around the transformer either.
All the best

Just following up on this.  Thanks for the replies.  Looks like the new updates are going to hit the mark anyways.  next question is how do I do the update without having to ship my zendrum to the States!!! :o
Have been playing on my trapkat and love the way I can pick an instrument from one vsti to play on one pad and then select a different vsti for a different pad (all on the same kit).  Now that you can do it on a Zen, portability becomes a new option again - I can leave the TK at home and take the LT.
Is shipping to USA the only option here?
Thanks

ZenChat / Re: foot pedal trigger
« on: May 11, 2009, 09:05:41 am »
Yep, I did something similar.  I bought a project box , a 27mm piezo and a mono jack socket from Maplins (UK store) plus an l-bracket from B&Q.  Bent the l bracket to a suitable angle to allow the inverted beater of the pedal to impact the entre of the project box when they were screwed together.  I then fixed the piezo to the internal top surface of the project box with double sided adhesive foam tape, drilled a hole in the side of the PB for the jack socket, wired the piezo (red lead to tip, black lead to earth), hot glued the soldered pads on the piezo itself since they are prone to breaking off otherwise; bolted the PB to the L-bracket - connected up the pedal and the cable to my module and voila!  Less than 12 euro for parts and 1hours effort.

Thanks for the responces gents.  Mustang, did I see you on the vdrums forum as well?  Good to know of at least one other zendrummer in Ireland.
Back on topic though, using my Drumkat I can select a midi output channel for each and every pad which is the ultimate in flexibility.  Would be a peach of a tweak to have on the Zendrum!
Onwards and upwards!

Thanks for such a speedy response!  I have a further clarification question though. If the midi channel is global across the complete set up, how would one go about remapping  the channel purely  by selecting a new patch via the interface (up/down arrow buttons).  For example, if I set up the 1st configuration for a drumkit outputting on channel 10 and then select the next patch up to work on percussion it would still be outputting on channel 10.  Would i have to externally mute the drumkit and solo the percussion instruments (both VSTi's by the way - ezdrummer Nashville and Latin ezx's) through the software interface (Toontrack solo)?  I ask because last week I was playing at a large youth event in Ireland and it would have been great to change patches on the fly between drums and percussion.  In the end, I alternated between a handsonic and the LT running vsti.  How would I control the audio output so that the same midi channel doesn't trigger both sound sources?  I hope this makes sense.
Thanks for your patience with a midi novice.
