MIDI Parameters

Control Panel

This isn't really a patch editor: it's a device meant to help you send CC, NRPN, RPN, and Pitch Bend messages to your synthesizer. I'll be adding to this and augmenting it over time. Once you've customized your CCs, you can save them to a sysex file and retrieve them later.

Communicating with Edisyn

Make sure you've got Edisyn set up to send to the right channel on your synthesizer.

About the CC Panels

The CC panels give you direct access to all 128 CC parameters: though perhaps you should only play with the first 120 unless you know what you're doing with the last 8.

Each CC parameter has a Dial where you can directly change its value, plus a Send button which lets you repeatedly send the current dial value. There is also an On checkbox: if you select this, then 127 is sent, else 0 is sent (the On checkbox also is selected when a CC value greater than or equal to 64 is sent via the dial). The CCs each have classic names, but you can change any of them: just click on the Name (or whatever it's called) button.

About the Custom CC, NRPN, and RPN Panels

These panels allow you to set up the panel to respond to custom CC, NRPN, and RPN parameters of your choosing. Why you'd need RPN is anyone's guess, but there you have it.

You select a parameter with the Parameter dial, and you can customize its name with the Name button. Each parameter has two value dials which you can tweak independently. The idea is that you can repeatedly send either of the values by pressing the Send or Alt buttons. Changing the dials will also send the parameters in question.

The dials may be 7-bit MSB-only (0..127) or they may be 14-bit MSB+LSB (0...16383), depending on the setting of the +LSB checkbox. For Custom CC, only parameters 0...32 are capable of being 14-bit (by sending the LSB at the parameter number + 32): the others must be 7-bit. NRPN and RPN of course can be either 7-bit MSB-only or 14-bint MSB+LSB at any time.

The On button will send either a 0 (off) or a maximum value (on), changing the Send dial. It also is selected automatically if the Send dial is set to above half-way.

About the Other Panel

This panel gives you access to Pitch Bend, a well as to the three standard RPN messages: Pitch Bend Range (or Sensitivity), Coarse Tuning, and Fine Tuning.
