It sounds like a small step to getting it all working,
I use SD2 (and have used BFDlite, EZD, Battery and other drum vsti's with my laptop).
To get you up and making some noise - start with Toontrack Solo again. I know you have it working but it won't hurt to record it here for posterity (and other users). And note that you will ONLY be able to play Toontrack products via the Solo interface - it won't host BFD etc.
- Open up Solo, you need to tell it where to find your files when you first open it ( a pop-up box appears - in the bottom half there is an option to set the path for your vst plugin for SD.) Identify where your .dll file is for SD VST - if you let SD setup dictate where this was it may be under the directory on your drive for Toontrack, nestling in a subdirectory. Alternatively, if you already have vst plugins you may have installed the .dll in there, so choose that as the option.
Solo opens with the default kit. Now go to make your default midi & audio settings.
- Open the Midi dropdown menu at the top and select your controller. Leave the channel set on Omni so it piicks up any midi input.
- Open the Audio tab. Select your interfaces option (presonus). For channels, stick with just 1+2 as the option, keeping it as simple as possible for now. For latency settings, start with 512 and see how you get on. You can gradually reduce it once you have some noises going on. For the mixer, you can open up the interface and see that the mute button is not checked (it shouldn't be) and that the channel input is set to Omni still by clicking on the arrowed dropdown menu under the level meter.
If you hit on a pad, you should see the level meter changing and should hear a noise (but hit several pads to make sure that the trigger is assigned to a sound in Solo just in case).
Now for your vst host programme.
Open it up and look for the audio and midi preferences tabs. Most have them in the "options" or "preferences" tabs somewher in the title bar. Follow the same kind of logic that we have applied to using Solo above. Ensure that midi input is set to omni wherever possible to start with. In the audio settings, look for a description that includes your interfaces name and also indicates the output channels -remember what this says,
Open up your drum plugin. With ezdrummer, when it is loaded, mouseclick on a drum pad and see if you hear any noise. If yes, then you can try drumming on the zen. if you still hear noise - happy days!. Configure your pads and dwell in sonic nirvana.
However, if you can hear noise when you click on a pad with your mouse but not when you play your zen then the plugin is not receiving midi siganls. in the channel options that the plug in is inserted into, click on the midi tabs and make sure that they are set to receive midi throughyour midi interface and via the Omni setting. Play the zen again - it should work now.
If you see the channel meter now moving but don't get any audio then the output for audio needs configuring correctly. In the channel strip options, there should be a setting to choose audio device and audio channels. Make sure htese are set to the same settings that you configured for the host programme in the Main Preferences /Options pages.. now try again, you should now hear sound as you play your zen.
See how you go with this. Save your setting with the project!
if this still doesn't work, don't give up. Just exit the programme, reboot the pc and start your host programme again. Some software is fussy and needs to be exclusively open to make things happen correctly. Check all the above again and then try playing.
All the best - it will definitely be worth it in the end. Persevere, me heartie!
