hi,
i try to read an evolver/polyevolver program dump request (228bytes)
in the synth manual :[i:2rscle1l]220 bytes in “packed MS bit†format (see page 54). Includes 128 bytes of
Program parameters and 64 bytes of Sequence data[/i:2rscle1l]and in the CTRL documentation :
[i:2rscle1l]the data to unpack (this must not include the MIDI SysEx prefix or suffix, and must be a multiple of
[/i:2rscle1l]a multiple 8 => i think number of Bytes => but : 220 is not a multiple of 8.
What range do i have to use[code:2rscle1l]programData = midiMessage:getLuaData():getRange(7,220)
unpackedData = utils.unpackDsiData(programData)[/code:2rscle1l]i’ve tested with various ranges, and it doesn’t give me a good result.
thanks
something strange
[code:1kopo6z5]programData = midiMessage:getLuaData():getRange(7,
unpackedData = utils.unpackDsiData(programData)[/code:1kopo6z5]unpackedData and utils.unpackDsiData(programData ) to HexString doesn’t give the same result
I don’t know how the implementation works in all DSI devices, the unpack/pack routines were taken from the prophet forums (my old code from Ctrlrv4 got lost and i can’t find it), i can assume that the data does not have to come in 8 byte packets, but that’s what the manual says for the Evolver and the Mopho, it might be different for some other devices.
for the evolver it ‘s some thing like that : for a serie of 8 bytes :
if the real value of byte 1 is > to 127 then byte 0 =1
if the real value of byte 3 is > to 127 then byte 0 =4
if the real value of byte 4 is > to 127 then byte 0 =8
if the real value of byte 3 and 4 are > 127 then byte 0 =0C (12)so now i ‘m trying to make a own function
from what i understand it’s in 8 bytes packets, last 7 bytes are the values of parameters with the msb bit stripped and put in the first byte at the beginning of the packet.
most important, it’s a programming language if something is not working the way i did it, do it yourself, and if possible share with others, that’s the whole point.
