NRPN hardware controller for OB-6?

NRPN hardware controller for OB-6?
« on: February 06, 2021, 01:09:13 AM »
Greetings everyone,

I am looking at controlling my OB-6 with a hardware device which can send NRPN messages.

I have been trying with an arturia beatstep pro, which unfortunately didn't work out because of incompatibilities in how the nrpn protocol is set up for both machines.

I asked the sequential support for suggestions for hardware/physical controllers which are well suited for the OB-6, but even they didn't have a clue (they could only suggest software).

Hopefully some of you out there has some first hand experience or a tip?

Thanks!

I wouldn't see why the NRPN would be any special with the OB-6? I use a Behringer BCR2000 (old model, used only) with great success. It is extremely flexible and can even do sysex for other synths that don't do NRPN.

Here is a template I made to control the gated sequencer of the Rev2: https://github.com/christofmuc/bcr2000_for_dsi_prophet_rev2 as an example.

Hey Kris, thanks for getting back to me. Great about the Behringer BCR2000 and for the link, I guess that should work just as good on the ob-6. It seems to me that both Rev2 and Ob-6 handle NRPN the same way.

What would the advantage be? Although I am new to this, I was hoping to:

a) have control over all parameters, not only those supported by CC
b) have higher resolution (higher than 127), even on those parameters which are supported by CC

Do you think using NRPN won't be that special on the ob-6? Why is that special on the Rev2?

thanks!

I don't think the synth would support the higher resolution available via NRPN. I think the encoders on the synth produce the same 127 data range, and the sysex memory for sure is 127 resolution. For remote controlling of course CC is limited by the number of available controllers, and to get to all parameters you need NRPN (you can even send NRPNs to change global settings...).

The OB-6 is much more immediate than the Rev2, so I am not sure how much an external controller would give you? The Rev2 on the other hand for example has all the gated step sequencer data lanes which I edit with the BCR2000. All other parameters I still edit on the synth. It never occured to me to use the BCR2000 with the OB-6, because I think it has a knob for each function already? (At least the keyboard version, which is what I have).

Yes, if you are able to control it manually it makes no difference. But it would be great to have an external controller modulate via LFO or automation a bunch of NRPN parameters while you are playing. If NRPN allows for more subtlety it is a great resource. I will look into the BCR2000, whether you can assign a few parameters for LFO modulation via NRPN. I have an Arturia Beatstep pro, which unluckily doesn't allow that.
