Midi interface for Organs, String Machines and Polyphonic Synthesizers
In addition, parameters such as filter cutoff, glide or preset selection switches can often be interfaced as well.
The modular approach lets you add as many analogue switches as needed. This allows even large polyphonic synthesizers or organs with several manuals to be interfaced.
We offer OrganDonor as customized versions for particular synthesizers. We are working on expanding the portfolio and creating more installation manuals. Contact us if your synth is not on the list yet, or if you want OrganDonor installed in your synth by us.
Additionally, the behaviour of OrganDonor is fully customizable via the OrganDonor configurator. This is a browser based tool that allows you to create midi assignments to analogue switches, digital outputs, PWM outputs and CV/Gate output (special OrganDonor version needed for CV-out).
