Way to set note division LFO from midi CC?

Postby ibuystudiogear » Fri Feb 14, 2020 12:31 pm

I'm using a Behringer BCR2000 to program the Uno Synth and I've got every CC mapped. Every CC but one. For the life of me I can't get the LFO sync to turn on giving me the 1/4, 1/8 note etc divisions. I've sent it midi clock with the Uno set to slave. I just can't figure it out. Is there an unprinted midi CC to get the lfo sync to come on without the editor?

A very un-official solution....

Internally the LFO rate is stored as 14bit value in the preset, which also means that rate can finer grained that can be achieved with Knob or CC.

There is a SysEx message which can set just the LFO Rate to the active program (ie. not written to patch memory).
Code: Select all
$ amidi -p hw:1,0,0 -S 'f0 00 21 1a 02 01 30 00 01 20 22 7f 7f f7'
                                                         ^^ ^^ Param Value
                                                   ^^ ^^ Param ID
                                                ^^ Param count


This lets the divisions be set as follows
Code: Select all
1:1 = 16383 (0x7f 0x7f)
1:2 = 16382
4d  = 16381
1:4 = 16380
8d  = 16379
4t  = 16378
1:8 = 16377
16d = 16376
8t  = 16375
16  = 16374
16t = 16373 (0x7f 0x75)
