v0.2.1-beta

Ribbon control effects Analog Delay

In this release the ribbon controller is changed slightly. The ribbon no longer has a GLIDE control, and instead the potentiometer at this position now attenuates the ribbon control signal to the Analog Delay. This allows for some weird delay modulations and also allows the delay time to track with the pitch of the VCO.

These files result in a working instrument that has been used for several performances at the time of this writing.

A few small issues, PCB kludges, and enhancements remain to be addressed in the future.
The VCF/VCA/BBD board needs some small kludges
The VCO board needs some small kludges and has some un-ideal (but workable) behavior
Ox has requested an on/off switch be added to the MODOSC evantually

v0.2.0-beta

Early 2023 Enhancements

This release adds an analog delay and quantized ribbon controller, features Ox has been wanting for a while.

With the addition of the delay and digitized ribbon the instrument sounds great and is very fun to play. These files result in a working instrument that has been used for several performances at the time of this writing.

A few small issues, PCB kludges, and enhancements remain to be addressed in the future.

• The VCF/VCA/BBD board needs some small kludges
• The VCO board needs some small kludges and has some un-ideal (but workable) behavior
• Ox has requested an on/off switch be added to the MODOSC evantually

Initial Summer 2022 refurb

These are the files for the synth after its first big rufurb in Summer of 2022. The synth was initially constructed on protoboards, this refurb replaced all of the circuit boards with professionally manufactured PCBs, and added much needed documentation.

However, there are still some improvements to be made.

• The final VCA which controls the volume does not decay as smoothly as we would like.
• The main VCO has a few small bugs, and needs a few minor PCB kludges to work.
• There are a handful of other small issues and enhancements under consideration.

These files will result in a working synth, and a version has been built and used for several performances. But expect gradual improvements to the design.
