At the moment, there's a lack of real drum synthesizers in the Linux Audio world. Drum synthesis instead of sampling is important to emulate the dynamic sound of -for example- the TR-909 hand clap, which is generated out of white noise. You can find some patches for Alsa Modular Synth here: https://sigterm.demon.nl/~stanley/drumsynth/ Most patches don't sound like the real 808/909, because they need some/much more tweaking. Feel free to improve the patches. I'm now trying to decipher the original schematics of the TR-909, my aim is to write a separate 909 softsynth (clone), because Alsa Modular Synth is too limiting (difficult/impossible to create drum maps, difficult to handle multiple instances of AMS, etc) Regards, Stanley Jaddoe
