OT Nrpn with external hardware synth

Hi,

When trying to send those 3 CC to trigger a mini nova synth animate button

cc1: nrpn 99 with the value 60
cc2: nrpn 98 with the value 0 to 7 for the button i want to use
cc3: DATAENTR 6 with the value 127 or 0 for pressed or not

I have to press twice the stop button on the octatrack to effectively trigger the synth. It looks like the trigs on the midi sequencer isn’t doing its job correctly …

How to make it work without stopping the sequencer to update the synth ?

Thank you !

Hi,

I’m not sure why you are setting 99 and 98 to different values - this may be your problem. However, I don’t know anything about the Mininova I’m afraid.

In my experience (with NRPN on the KS Rack and Supernova), I set the 3 controllers as follows:

CC1:99 = 60 or whatever CC number you want to control

CC2:98 = 60 (same as above)

CC3:6 = 0-127 (the value of CC2 and CC3)

So basically, CC98 and CC99 values are the same, (sent as a pair) and CC6 value controls the value of CC99 and 98 (controller number 60). In your case, CC6 value should be between 0 and 7

Hope this helps.

It’s absolutely valid to have different value for 99 & 98 !

[li]Aren´t the CC#s sent on pattern changes either? I e if you alter these settings on your mini nova synth, then select another pattern on your OT and then re-select this pattern (with these CC#s setup). Your synth won´t update?[/li]
[li]If you set more trigs with the same CC#s but with different values (0 or 127), your mini nova synth doesn´t respond to these other OT transmissions either (thus altering the ON/OFF state of that button)?[/li]
[li]If the value (= state of that button) is already active, is/would your synth updating anything if the trig got the same value too?[/li]
[li]Can you see any kind of MIDI reception at your mini nova synth?[/li]

Maybe, but I can successfully change NRPN parameters with CC99 and CC98 set to the same number. For example, with my Supernova I set 99 and 98 values both to 96 which allows me to control the comb filter boost - using CC6 to control their value…

From Wikipedia -

‘Unlike other MIDI controllers (such as velocity, [url=“http://en.wikipedia.org/wiki/Modulation”]modulation, [url=“http://en.wikipedia.org/wiki/Volume”]volume, etc.), NRPNs require more than one piece of controller data to be sent. First, controller 99 - NRPN Most Significant Byte (MSB) - followed by 98 - NRPN Least Significant Byte (LSB) sent as a pair specify the parameter to be changed’

Hi all

I’ve got a Moog RME Voyager which I’d like to sequence from the OT’s MIDI outs.

I’d love to be able to do some conditional filtering / have some p locks on the cutoff, but the Moog doesn’t have a single CC for that, rather it has the MSB / LSB system for stepping up smoothly / in higher res (much like the A4, in fact).

Can anyone think of a good (and easy) way of doing this? I could program two CCs, I know, but it’s not exactly intuitive, or quick, when you want to throw in a quick ‘higher cutoff’ step…

Try MSB only. Anyway with OT it seems difficult to send MSB + LSB with one or 2 knobs smoothly…

Maybe have an LFO constantly sending LSB (a relatively small range) so that whenever you send MSB, it sends as a “pair”?

It can be interesting if the Moog needs MSB + LSB.
