I may be missing something, but when using key split I cannot find a way to allow "thru" the input notes from in the filtered out region of the keyboard.
When using key split, it would be nice to allow thru for the input notes aren't in the active arpeggiator region (high or low). Perhaps it could be a new option under Midi Thru for "On (in key split)"?
Yes, normally I keep MIDI Thru OFF to play ARP, although I can see why Thru ON has it's uses
Specifically I would like to use keyboard split to play ARP on one side and normal non-arpeggiated notes on the other. For example playing bass notes with my left hand under an arpeggio on my right, or playing a melody with my right hand over a lower arp/sequence.
Currently this can only be done by handling all the key splitting and note filtering externally outside ARP. It looks like this might be implemented in ARP as an additional "split" MIDI Thru mode where the filtered notes (the ones not contributing to the ARP chord notes) are allowed through unchanged.
The ARP is designed to pass through all MIDI notes from your keyboard when MIDI Thru is enabled - this includes notes from both sides of any keyboard split you've set up.
I've just tested this with the V8 firmware and can confirm that all notes are passing through correctly.
Could you clarify what you're trying to achieve? Are you looking to prevent certain notes from passing through - specifically those within your active split region?
