FH-2, MPE and Envelopes

Author FH-2, MPE and Envelopes

I'm struggling with getting my ROLI Seaboard to control my modular setup. I have an FH-2 an FHX-1 and an FHX-8GT. I have a USB hub connected to the A input of the FH-2. The ROLI and a Novation Launch Control are connected to the hub. The ROLI is powered by a wall wart. The "A" on the FH-2 display shows two devices connected. (Usually... but that's a question for another time. Let's assume for now that it's good.)

I would like to use the ROLI in MPE mode and have the FH-2 process the pitch(CV), gate, aftertouch and Y for four voices, adding envelope information. I am confused about how to configure things to accomplish this.

In the web interface I
select the first output
change the type to MPE
set the base output to 1
check boxes for CV, Gate*, Envelope and aftertouch
choose CC 64 for Y
set voices to 4 and
Last channel to 5

*I have tried this both checking gate and not checking gate, since I want to use envelopes and I'm not sure which is correct.

I'd like to use the knobs on the Launch Control to modify the envelopes on a per voice basis. When I turn a knob on the Launch Control the midi channel, CC number and value appear in the FH-2 display. I'm not sure how I should use this information to fill in the envelope section of the web app.

In the MIDI/CV converters section of the FH-2 manual, on page 19, it says that the envelope function is assigned an output last. (Rather than the order that the column appears in on the web app screen.) So, assuming four outputs for each voice (in the case where I don't check Gate, for example... because I would like to make use of my FHX-8GT someday) does this mean I should fill in the _4th_ line of the Portamento/Transpose/Envelope section with the MIDI channel number and CC number for each knob as they show up in the FH-2 display as appropriate for Attack, Decay, etc.
I've tried putting them in several different lines and nothing seems to work.

And what triggers the FH-2 to start sending the envelope out of an output anyway?

Obviously, my understanding is incomplete and/or just wrong. Maybe someone who has been down this path can help me out. At this point I'm just getting frustrated and I'd like to start making some noise.

Thanks for reading!

The envelope triggers whenever the gate/trigger does.

No. The lines of the Portamento/Transpose/Envelope section correspond to the lines of the MIDI/CV Converters section. (Both are numbered 1-16 for MIDI/CV converters 1-16.)

PS the envelopes should start working as soon as you've enabled them in the MIDI/CV converter. You don't need to map the CCs to change the envelope times for them to work - you should get envelopes with default times as soon as it's enabled.

Thanks for responding.

So, if I understand you correctly it is not possible to use a different envelope for each separate "voice" when a converter is in MPE mode? Does that mean that the one envelope affects all the MPE pitch/CV outputs? Or is it the one envelope affecting just the first CV output?

As long as I know what I am dealing with... I guess I can start exploring other combinations of MONO, POLY, etc.

Thanks

It's one envelope per voice, exactly the same as the poly mode.

Thanks. I guess that's perfectly reasonable.

Thinking further about what I am trying to do, when I get some time, I may experiment with using the note range converter parameters. Seems like I might be able to split the keyboard into regions with different envelope responses? Still working through the relationship between converters and physical module outputs... Either I need more expanders... or I should just stop trying to coerce my modular into a multi-timbral polyphonic synth.

Thanks again.

Hi BobbyFogtop,

did you finally get your answers?
My FH-2 just arrived yesterday and I'm also kind of lost regarding MPE.

I'd like to control my envelope with cc messages from my Digitakt and don't really get how to do it..

I was experimenting with different configurations for a while but it seemed like I was getting inconsistent results. At the time it seemed like I may have been having problems with my laptop and my keyboard as well as the FH-2. Frustrating. But mostly, I didn't have the time to focus on the issue, so it's possible the only problem was a lack of understanding on my part.

It would be great if there were somewhere one could go to find examples of different configuration setups. Someone should make a tutorial! Unfortunately, I am not that person.

Sorry I can't be more helpful. Good luck!

Use the 'Show Portamento/Transpose/Envelopes' section of the config tool. The rows correspond to the rows in the MIDI/CV section, so for example if you're using MIDI/CV converter 1, use row 1 in the envelopes section. Then choose the MIDI channel and CC of each envelope parameter you want to control.

With respect to MPE and Envelopes, I'm trying to setup a Sensel Morph, and wanted to try an envelope, with sustain controlled by Y (cc74).

The envelope setting wants a channel and CC; if this is envelope per voice, with mpe each voice is on a separate channel, so the envelope only works for 1 voice. Is this correct? (it seems to be working this way; I can get sustain from Y for first voice, but not for second).

I can setup the morph to send mpe as usual so it deals with note channels, then on the FH-2 treat it as multiple monophonic converters, each with it's own envelope, and that seems to be working. Is this the best way to do it? I think I just lose control over voice allocation-- any extra key presses are ignored, which is fine.

Above you mentioned the envelopes have defaults for the uncontrolled parameters -- is there a list of them anywhere?

Thanks,

Yes.

I can't immediately think of a better one.

You can view them in the module if you go into the edit preset menu.
