Anyone got polyphonic aftertouch working? |
|
|
I'm considering getting a Roland A-800Pro which (according to the manual) has polyphonic aftertouch. I understand the Andromeda responds to this.
Has anyone tried this and if so how did it work out?
It can sound like the CS80 - can it act like one ??? _________________ http://soundcloud.com/Mefistophelees |

no,
the manual says:
the a6 will react to polyphonic at, they never said when ....
so it's not implemented as far as i understand |

That's originally what I thought but there's a section in the Tips and tricks book that seems to suggest it can be made to work. It is a bit vague though. So that's why I was wondering anyone has tried it. _________________ http://soundcloud.com/Mefistophelees |

Sadly the A6 does not respond to polyAT. OS development ceased before they could get to it. |

Polyphonic Aftertouch on an Alesis Andromeda |
|
|
I have found a way to implement polyphonic aftertouch on the Alesis Andromeda using a MIDI controller with monophonic aftertouch.
You need a MIDI controller with mono aftertouch and the ability to transmit in MIDI Mode 4. MIDI Mode 4 is an accumulative monophonic mode, which means the MIDI controller will send key 1 on MIDI channel (n), key 2 on MIDI channel (n+1), key 3 on MIDI channel (n+2), etc. Your controller may have an option for number of MIDI channels in Mode 4, IE you can specify an upper limit of channel 8 so that other devices on channel 9 and up are not affected.
Say your Andromeda MIDI base channel under the Globals menu is channel 1. You want channel (n) on the MIDI controller to be channel #1. Under this configuration when you press keys and engage the aftertouch, your MIDI controller should send note on and mono aftertouch messages on MIDI channel 1 for key #1, the next key will be MIDI channel 2, the next key will be MIDI channel 3, etc. Every key will have its independent MIDI channel and mono aftertouch - an alternate poly aftertouch.
Configure a patch on the Andromeda that uses MIDI Aftertouch to modulate something - like the filter cutoff. MIDI controller mono aftertouch is equal to "MIDI Aftertouch" in the Andromeda modulation source list.
The Andromeda does not appear to have a MIDI Mode 4 so we need to configure a mix setup on the Andromeda with (n) layers, every layer playing the aforementioned patch. Layer one is assigned MIDI channel n, layer 2 = MIDI channel n+1, layer 3 = MIDI channel n+2, etc.
Unfortunately for Kurzweil MIDIBoard owners, there is a bug in the firmware in that all mono aftertouch messages are only transmitted on the first MIDI channel (d@mn!). Another MIDI controller may operate correctly.
But I did prove this concept by multitracking MIDI tracks on my seqeuncer using my MIDIBoard on different MIDI channels - and this works! |

seems like a lot work - damn shame
Even my humble Xv5080 responds to Poly AT, with nothing fancy needed to be tweaked. Every patch is ready to go. |
