Sending midi note to a patch with arp/seq on will play the note regulary, as if the arp/seq was not enabled (It can still be triggered from the minifreak keyboard)
It really limits external sequencing (ie. to trigger or transpose a sequence)
The microfreak arp/seq was following external midi note if I recall correctly.
Please bring this feature back
Ideally, having an "External control" setting similar to the internal one where the routing to the arp/seq can be toggled on/off would be quite flexible and useful as well.
