Metallic Rimshot

This is the same patch as the 808 rimshot with a few changes to the settings.

1: The oscillators will provide the body of the sound. Tune both to an inharmonic combination.

1a: Tune VCO-B to A4 -42 cents.

1b: Tune VCO-A to G#6 +6 cents.

2: Patch either the sine or triangle from VCO-B to mixer in 1. Then raise the mixer in 1 and 2 channels. Turn on soft clipping in the mixer.

3: Patch the mixer to the wave folder audio in, and raise the wave folder mod level amount quite high.

4: Patch the wave folder out to the filter in. Switch the filter to HP4.

5: Mult ENV-B to the wave folder CV in and VCA-A level in. Set the envelope rise and shape all the way down. Adjust the fall level as you fire the trigger. Keep the envelope tight, but let it ring out a little.

6: Raise filter resonance (Q), and adjust the frequency to cut the low frequencies.

7: Set Drive to taste.

Optionally: Turn on soft clipping in the output section.
