So, my friend Peter lent me his beloved TR-909 drum machine. After a bit of messing about, including tracking down an IEC C9 mains lead (from here), it's working, and is wonderful, particularly when messed about with. I already posted this G2 resonator patch, which is a copy of the effect in Ableton Live. Last night I made this patch (+ audio sample), in which the G2 tries to recreate the sounds it's getting at the inputs, using just a simple oscillator+filter. It sounds really wiggy, but somehow still a bit like a 909. Finally, and least interestingly, here [mp3] is the 909 coming through the spring reverb and VRS-23. Thanks, Peter!
