External Synth/Keyboard


#1

Hi, I’m looking through the MIDI stuff at present, as I’m trying to run Patterns from my SC whilst also playing lines/pads from an external synth (a Prophet, REV 2). I see in the help files that running a external keyboard from SC uses a Pbind Pattern chained to Pattern keys.

a = Pbind(\degree, Prand([1, 2, 3, [0, 5]], inf), \bend, Pwhite(0, 76, inf));

// chain a midi event into the pattern and play it 

(a <> (type: \midi, midiout: m)).play; 

// These keys don't seem to have an effect in the Pbind.

This indeed works fine, however, why is it not possible to run these keys straight in a Pbind itself? I’ve tried and hear it doesn’t work, but why is that? I looked at the Pattern help files, Pchain etc and see what’s happening, but somehow I must be missing something.

Thanks in advance.

I’m not completely sure what you mean by “run”, but assuming that you’re trying to control external MIDI hardware with Event Patterns, have you looked at Pattern Guide Cookbook 04: Sending MIDI in the documentation?

There’s nothing about sending MIDI that specifically calls for Pchain / Pattern composition, and everything should indeed be possible within a single Pbind.


#3

Thanks, hadn’t seen that. I’d been looking at the MIDIOut section, but was as usual not thorough enough in my search - in the help files. I thought I’d seen something elsewhere awhile ago…!


#4

On the side line: given that you have a prophet rev2, you may be interested in one of my projects to completely control all sound design parameters, as well as randomize parameters, play patterns, design envelopes, change tunings, and more via supercollider. It’s a work in progress, not enough documentation at the moment.

The GUI and the synth automagically remain synchronized if you modify parameters on either side.

It should work with recent prophet OS versions (on PC side it’s only tested on linux, but there’s nothing linux specific in the implementation as far as I can tell)

It also depends on another project of mine: https://github.com/shimpe/panola

One particularly interesting (I think) application that comes with it is the rev2editor, found as part of the included examples.

(Also make sure to configure the synth to listen to and send out NRPN midi messages)


#5

Wow, Shiihs, looks very interesting, I’ll head over to Git and take a look. I don’t have time now to try it out but will certainly look over it next week.

Thanks.

p.s. Any recordings (Soundcloud etc) using this set-up?


#6

Well shiihs, I was so curious I ended up installing the quark straight away, however I’m not getting anywhere, so maybe a little help is needed.

I tried running the various midi commands just to check all is there:

MIDIClient.init;
which produces the normal:

-> a ScProphetRev2
MIDI Sources:
MIDIEndPoint(“Rev2”, “Rev2”)
MIDI Destinations:
MIDIEndPoint(“Rev2”, “Rev2”)
-> MIDIClient
-> a MIDIOut

I then tried running you example:

(
~synth = ScProphetRev2.new;
~synth.connect;
~synth.get_patch_from_synth(5, 1, { ~synth.patch_explainer.join("\n").postln; });
)

but only get:

WARNING: couldn’t find MIDI endpoint. Connect failed!.
WARNING: Cannot send commands to synth because not connected yet.
WARNING: Call connect first.
-> a ScProphetRev2

As you can see, SC sees the endpoint, so why am I getting this failed message? Can you give me a little help please. By the way (just in case its important), I’m on a macbook, and connecting via USB to the Rev2.

Thanks in advance.


#7

The piece in the following link was generated by letting supercollider drive the rev2 using only the most basic functionality provided by the system: https://www.youtube.com/watch?v=bJYCof3ViLk but it does nowhere near show all the possibilities of the system.

I haven’t recorded any weirdness yet (although I have heard plenty of “interesting” things while using the system already), but in the future I hope to make some screencasts demonstrating different features.

First the KDE FileDialog hangup bug will have to be solved though because it’s kind of a disaster having the system freeze during recording of a screencast and then having to restart because data entered into the system is lost etc

One of the features is to automatically randomize all kinds of parameters on the synth while playing patterns (it has a 16 voice polyphonic sequencer built-in (which allows not only to sequence notes but also to change all parameter values like cutoff or resonance while it’s playing) and which you can use in combination with the synth’s own gated sequencer for generating interesting sequences) or while playing live. It can lead to the weirdest sounds being generated - things you wouldn’t think are possible by just turning the knobs.


#8

Sorry I have been offline for a while.

You could try to update from git, then call “connect” with the name parameter. Code connecting to midi endpoints seems to be a bit of a challenge (and unfortunately I don’t have other OS at the moment to test it at my side)

(
~synth = ScProphetRev2.new;
~synth.connect(name:"Rev2");
~synth.get_patch_from_synth(5, 1, { ~synth.patch_explainer.join("\n").postln; });
)

#9

Brilliant, I’ll try it and get back to you.

Thanks.


#10

Ok, I tried it, but no luck, same as before - can’t find endpoint.


#11

AArrrggh this is annoying :slight_smile: When you posted the output of your MIDIClient.init, did you copy paste the output into the forum or did you type it out from memory?

So I updated the code on github again, and added some debug code. Can you try the following?
For device, use the first part of the MIDIClient.destinations endpoint, and for name use the second part of the MIDIClient.destinations endpoint.

For example, if

MIDIClient.init;
MIDIClient.destinations;

gives

MIDI Sources:
	MIDIEndPoint("System", "Timer")
	MIDIEndPoint("System", "Announce")
	MIDIEndPoint("Midi Through", "Midi Through Port-0")
	MIDIEndPoint("Rev2", "Rev2 MIDI 1")
	MIDIEndPoint("SuperCollider", "out0")
	MIDIEndPoint("SuperCollider", "out1")
	MIDIEndPoint("SuperCollider", "out2")
	MIDIEndPoint("SuperCollider", "out3")
	MIDIEndPoint("SuperCollider", "out4")
MIDI Destinations:
	MIDIEndPoint("Midi Through", "Midi Through Port-0")
	MIDIEndPoint("Rev2", "Rev2 MIDI 1")
	MIDIEndPoint("SuperCollider", "in0")
	MIDIEndPoint("SuperCollider", "in1")
	MIDIEndPoint("SuperCollider", "in2")
	MIDIEndPoint("SuperCollider", "in3")
	MIDIEndPoint("SuperCollider", "in4")
	MIDIEndPoint("SuperCollider", "in5")
	MIDIEndPoint("SuperCollider", "in6")

You’d use

( 
~synth = ScProphetRev2(); 
~synth.connect(device:"Rev2", name:"Rev2 MIDI 1"); 
~synth.get_patch_from_synth(
    5, 1, { 
       ~synth.patch_explainer.join("\n").postln;
}); 
)

#12

Okay, trying your new version from Git, still getting an error, but not the same. As you can see ScProphetRev2 sees the endpoint:

MIDI Sources:
	MIDIEndPoint("Rev2", "Rev2")
MIDI Destinations:
	MIDIEndPoint("Rev2", "Rev2")
-> MIDIClient
-> [ MIDIEndPoint("Rev2", "Rev2") ]

but when I initialize the code as you suggest, this comes up:

check midi endpoint looking for Rev2: Rev2

Ok that may actually be better news than it seems.
I think I removed the patch_explainer functionality from the ScProphetRev2 class and into its own PatchDumper class at some point (but forgot to update the documentation). This is very much a pre-alpha quality, sorry about that.

Now instead of using that example, we could feel adventurous and try to open the rev2editor from the HelpSource/examples/ folder, and edit line 8, which currently still states:

p.connect;

to

p.connect(device:"Rev2", name:"Rev2"); // or whatever you had to type to make it connect in the smaller example

Then try to run it, and see if the system comes up.


#14

Also, where did you find my example? In the HelpSource/examples folder there’s one that should work (maybe a bit less ambitious to see if we get this one running first :slight_smile: ) :

(
~synth = ScProphetRev2.new;
~expl = PatchDumper.new;
~synth.connect; // edit as needed!
~synth.get_patch_from_synth(6, 120, {
	~synth.get_global_parameters_from_synth({
		~expl.patch_explainer(~synth.rev2, ~synth.rev2_nrpn_globals).join("\n").postln;
	});
});
)

#15

Ok, still not working, but looks as though its nearly there (from the read out):

This time it sees the Rev2 and reads its parameters. So what’s (or where’s) the ‘at’ problem?

Thanks for all the work you’re putting in.


#16

I’ll have to check when I’m back from work, but do you know which version of the Prophet OS you are running on your rev2?


#17

Same as you, I’ll check when I’m back from work. But I’m still running one of the original versions (bought mine about a year ago) - it’s an 8 voice, not 16 like yours.


#18

Ok, just checked my OS version (Rev2): is 1.1.4.27

So, tried running the above code again, but no luck, same message:
