hello fran!

thanks for your replies. i took my oberheim at a friends place, since he
owns midiquest and i got the vibrato speed down to a much more useful
level (it was 40, now 35). i am familiar with synthesis, so creating
sounds with jsynthlib for example is not hard at all. midi on the other
hand is just something like a neccecary evil to me. all this deeper
level sysex stuff is a bit difficult to grasp.


i tried MatrixEd when i got my M1000 but somehow i felt that the layout
and patch organizing with JSynthLib was just better for my tastes (altho
the EG curve settings are a bit bluky to operate sometimes).

i just want to use the two lfo:s to do all kinds of other stuff, and
then have the basic vibrato feature on the mod wheel. makes it a 3 lfo
synth in my book. that's one bad thing about the matrix that you can't
edit all the globals from the face, since they already gave you the
option to edit the pitch wheel sensitivity and unison mode. well...
still a great little poly, and now a little bit better because of a much
more "musical" vibrato setting.

thanks!

> I looked again at the midi implementation for the Global Parameters and there is no Global Vibrato Speed message and you're right I don't see a Global Editor in JSynthLib. These messages are detailed in the help section of James Clark's MatrixEd editor. I have a copy of this editor if you want to try it but again no global editor.

Below is the location for the nibblized data however the message needs a checksum for the last byte before the F7. More fun as I'm not sure if the Matrix will reject the data if the checksum is wrong! "nn nn" will be "00 00" for Vibrato Speed 0 and "0F 03" for 63. "0A 01" is 26 and "08 01" is 24 etc...

Save your original dumps in case the invalid checksum trashes anything. Also if you are making subtle tweaks to the Vibrato Speed you can subtract the value from the original checksum and try that.

>> The LFO Speed range is 0-63 in decimal or 0 to 3F in hex. For LFO1 speed 0 JSynth sent F0 10 06 06 50 00 F7. For LFO1 speed 63 it sent F0 10 06 06 50 3F F7.

>> The youngmonkey site lists the midi ID for LFO1 Speed as 80 decimal or 50 hex which agrees with the messages sent by JSynthLib. The LFO2 Speed listed has a typo as it says LFO1 Speed. No matter, LFO2 Speed is 90 decimal or 5A hex which again agrees with JSynth.

>> If this is not clear or needs more explaining feel free to contact me and we can discuss this further. I'm thinking that the relationship between the LFO speeds and Vibrato was the answer you needed but since you mentioned the midi noob thing I explained the messages anyway. JSynthLib can be a real pain to setup and use so I admire you for getting through all that.
