So far it only allows you to control all the params but DCO1 and Filter1.
Extending to DCO2-4 and Filter 2 is easy but I am no artist - so just wondering on best layout.
In C# I wrote another panel for K4. There I am experimenting with using a 1 - 4 for the DCO and 1 - 2 for filter, then remember the state so rendering/internal values are consistent.
And I will probably make a BCR2000 panel too.
Next steps on the K4 Ctrlr - understand how to handle sysex dumps so as to render panel and load/save to Synth,
Happy to accept beta testers / artists help!
