When I heard of the ARP, I salivated at the thought of four arps in a box. I had been using two separate boxes arpeggiating data and struggled with getting them to play nicely together. Alas, the ARP is only capable of listening to a single source of data for all of the internal arpeggiators to listen to. Disappointed, I opted to try and work around this limitation. I feel I've given it a fair shake, but I still am unable to achieve the results desired. Hence, I'm asking if a slight modification could be made.
Currently, the Global Menu in Set-Menu allows for a Sync to be selected that gets routed to all four arps. I propose adding an additional feature to the MIDI Out button which could set the source of data for that particular arp. I know it would be confusing, but a second press of MIDI Out could call a MIDI Sync In for each arp. Default would be G, for global which is set as is currently implemented via the Set-Menu button. But, it could then be modified per arp to a particular channel - different than the global setting.
For example, the Global Menu could have Sync set to channel 5, with the four arps set to:
ARP 1 = G
ARP2 = G
ARP3 = 7
ARP4 = 13
This would result in the box responding to data on three different MIDI channels (5, 7, & 13).
This would greatly break down the barriers I'm currently banging my head against in using this fantastic Midicake ARP device.
