Eurorack: better mallets with Rings

Using the built-in exciter in Rings is... okay, but doesn't really sound like a nice xylophone/glockenspiel. This does, more or less:


Set up Rings in 4x polyphony (red LED) and modal mode (green). Tune frequency to about 12 o'clock, or possibly an octave up around 2; Structure at about 2, Brightness at about 1, Damping and Position about 12 o'clock.

Set up a triangle VCO with V/OCT controlled by keyboard, tuned about 2-3 octaves below Rings. Modulate the VCO frequency with a fast decay envelope (adjust the amount and rate to taste). Use a slower, but still fast-ish decay envelope for the VCA.

Run that into Rings' audio input and mult the same V/OCT into it.

Adjust everything to taste (particularly the pitch envelope amount/speed, Brightness and position). You may also want to mult V/OCT into the Brightness CV input and set the attenuverter negative, so that higher notes are not quite as piercing.

You can probably use a kick drum module in place of the triangle VCO. :mrgreen:


For comparison, here's how it sounds disconnecting the input to Rings and just using the default exciter:

Hammered dulcimer variation:

Use a square VCO. Set Rings to sympathetic strings mode (yellow LED), Structure to 9 o'clock, Brightness 3 o'clock or higher, and Position about 3 o'clock. Give the pitch envelope just a taste of attack time. Plenty of stuff you can adjust about this too.

This was cool to try.

I've been doing a similar trick with my guitar into Rings:

I put the guitar through an envelope follower.
Then I take the envelope and use that to open a VCA that sends the guitar to Rings. Set the VCA to slightly exponential, and just the plucking transients get sent to Rings input.

It's a trick I learned from Patch&Tweak called Peak Processing (p246).
