![]() The attraction of the obliquely-named ME25S Note Separator is that even when used with a monotimbral synth transmitting on one MIDI channel, it offers you the possibility of multisplit textures. ![]() "Its attraction is that even when used with a monotimbral synth transmitting on one MIDI channel, it offers you the possibility of multisplit textures." It's worth noting, though, that seeing as not all MIDI instruments will respond to this command, its effectiveness can't exactly be guaranteed. When you change Banks on the ME30P, however, the unit sends the MIDI 'All Notes Off' command on all its outputs, which can be a useful safeguard against such a situation. In contrast, the 360 Systems Patcher listens for its patch changes on MIDI channel 16 of input 4.Ī possible danger with this sort of unit is that routings may be changed while notes are still playing, which means slave instruments never receive MIDI commands telling them to stop playing those notes - which in turn means that, depending on the envelope characteristic of the sound(s) playing, you'll get a MIDI drone. In the latter case, patch changes are registered on MIDI input D only - though as you can't define a specific channel on which the patch changes will be received you can't, for instance, devote a specific sequencer track to calling up ME30P routing configurations, which would be an obvious ME25S application. routing configurations) can be stepped through by footswitch or called up by MIDI patch changes. When you press the selector button for a particular input, a note A is sent on all the outputs associated with that input - useful. ![]() Akai have, however, thoughtfully included a facility for checking which instruments are slaved to each of the inputs. Operation of the ME30P is very straightforward, though the 360 Systems MIDI Patcher is easier to follow in that you can see at a glance from the front panel which outputs are assigned to each input. Where the input selection comes in useful is in allowing you to switch control from one keyboard to another or to a sequencer. With the above proviso, each MIDI input can be routed to any selection of the eight MIDI outputs. This would require the ME30P to be able to merge MIDI data, rather than merely route it. All four inputs can be channelled through the unit at the same time, but you can't send more than one input to the same output. These are the areas Akai have addressed with their latest offerings in the ME series of 19" rack-mounting MIDI units, the ME30P MIDI Programmable Patchbay and ME25S MIDI Programmable Note Separator.Īkai's MIDI patchbay is a four-in, eight-out unit with 15 programmable routing configurations. The other is for a unit which can provide a multisplit capability for playing slave instruments from any master instrument (a facility provided by some controller keyboards, such as the Oberheim Xk). One is for a flexible routing system which allows keyboards, drum machines and sequencers to be interconnected in a way that minimises the need for daisy-chaining, obviates the need for physical repatching of instruments, and allows the system to be reconfigured as required. Quote A couple of specific desires seem to be common among users of MIDI systems.
