Midi messages

Page updated with firmware 2.08.

This page explains what midi messages the preenfm2 can send or respond to.

You can select in the menu settings what midi messages you want the preenfm to respond to (none, CC, NRPN, both) and what midi messages you want it to send on its midi output jack when you modify a parameter (none, CC, NRPN).
If Usb midi is set to « In/Out » then the output will also be sent to your USB midi connection.

The preenfm2 responds to several well known midi messages such as :

  • Hold Pedal (CC#64), do not listen anymore to note off.
  • Keyboard pitch wheel, global after touch and modwheel (CC#1) can be routed in matrix sources.
  • Realtime midi clock (time clock, start, stop, continue)
  • Program change
  • Bank select (CC#0) and Bank Select LSB (#32)
  • Bank select=0 =>  BankLSB=Preenfm bank number
  • Bank select=1 => BankLSB=Combo number
  • Bank select=2 => BankLSB=DX7 bank 0->127
  • Bank select=3 => BankLSB=DX7 bank 128->255
  • Onmi On (CC#124) and Omni Off (CC#125). Allow an instrument to listen to all midi channel.
  • All sounds off (CC#120) mute immediatly all voices
  • All note off (CC#123) send note off to all voices. Release stage will be heard.

Sysex can be used to store and restore single presets. This sysex is not really usable outside the preenfm2. It contains a memory dump of the the preenfm2 memory. Set of 32 bits floating point numbers split in 7bits messages.

The preenfm2 will  flush all its parameters with NRPN midi messages if it recevies a NRPN with ParamLSB = 127 and ParamMSB = 127. Can be used by editors to read the preenfm2 current preset.

The following table shows with more details the parameters, their NRPN param number and values as well as the midi control change if available.
