Midi Input other than Channel 1

Things you could try: 1.) The JS MIDI router should work - make sure you have it as the first plugin in the chain before the VSTi or it won't work. 2.) Try Minihost or Cantabile (or any other host) to make sure your keyboard is even transmitting on other channels. Maybe something is wrong with it. 3.) Disable other MIDI inputs (if any) and all MIDI outputs to make sure nothing interferes there. 4.) Delete "reaper-midihw.ini" in the Reaper user folder (C:\Documents and Settings\<username>\Application Data\REAPER in order to force a device rescan, you probably have to enable the Keystation for input again after that. Even if your keyboard does only transmits on one or certain channels, using a channel as MIDI input (and for recording the MIDI) and sending this to the VSTi does the same as the JS MIDI router when you set the input to "all" and the output to channel x. This is also the way how Reaper creates multiple input channels (e.g. for multitimbral VSTi) automatically: - Open the FX chain window and select this: This generates 16 channels MIDI to the VSTi, each routed automatically to a different MIDI channel 1-16. Delete the ones you don't need.

Many thanks too. But 1. minihost works fine with my ext usb kb 2. JS IX/MIDI_Router does nothing whatever is the vsti placed after. 3. the split method works fine, bur every notes are channel 1 recorded. 4. it works fine w Cubase or Tracktion...BUT I LOVE REAPER !!!

That's it ! When I set the midi input via my usb kb (in the menu under the volume button, at the right of the "in" buttin), and choose another midi channel than 1 or All, no signal is sent to the track...

d.bop, you're a lord !! That's the setting of the keyboard ! I've never been facing it for years using Cubase or any other DAW. REAPER is great but some surprise may occure...That's part of its charms !Many thanks to all who helped. Talk to you later, for sure !!!
