One of our blind users had a a keyboard that sends a large number of
controls as NRPNs. For some inexplicable reason it sends some of them as lsb
only, but still sends all four bytes! This presented a problem, as to get the
0-127 range (but high res) we convert to floats then divide by 128.0
Well there is now a solution. A new MIDI-learn switch to treat it as an
ordinary 0-127 value. You have to use this after learning the control, as there
is no possible way to guess it. Currently it's only available via the command
line as I have worked out the best way to integrate it into the GUI - although
all the code is in place.
For those interested, using just the CLI you currently have to initially set up
a learn via direct access at the prompt. e.g.
yoshimi> direct 0 3 0 240
yoshimi> Learning
{twiddle controller}
yoshimi> Learned
yoshimi> CC 7 Chan 1 Main Volume
yoshimi>
Then make your adjustments:
yoshimi> s ml @1 min 60 - sets line 1 minumum to 60
yoshimi> Min = 60
yoshimi> s ml @1 bl en - block any others getting from this combination
yoshimi> Block enabled
yoshimi> s ml @1 ch all - set to recieve on all channels
Lines may be re-ordered
yoshimi>
yoshimi> Chan = All
yoshimi>
As usual, extensive details in various docs :)
