DR110 HH and CLAP

More looking at schematics of old drum machines I'm afraid Rolling Eyes

The Boss DR110 high hat was different enough to try out. The manual gave the exact frequencies of the 4 square wave oscillators. The original uses a CMOS 4006 shift register for noise but it is clocked at 80KHz, which we can't do on the G2. I just used a regular noise oscillator instead.

The clap is similar to other Roland/Boss designs but the manual gives exact values for all the envelope and trigger times. I've added a little clipping to both the triple triggered initial claps, and the final signal.
