well, im by no means an expert, nor can i claim to fully understand the vrg, tbph, but it can do

gated slews (ie slides, like tb303)
assymetric lfos (fast up, slow down etc)
AR envelope
AD envelope
A sub-octave generator (in certain cases, bit over my head but does do fun things)
basic vco (not 1v/oct)

and probably a lot more.

As i said, im no expert, perhaps paul krisp1 and or tony allgood could expand on this?

this thread has some more info too

Another vote for Oakley VRGs. Get two.

I have two, in MU format, and they've gotten moved to front and center because I find them so darn useful.

i cant remember the specific patching (its in the user manual) but basically when you apply a gate to the gate input it slides, and when you dont it doesnt! :party:

Simple -

Buy an Oakley VRG or two.

Patch the pitch CV in on "Slew In", take your glissando pitch CV out from "output".

I get a nice glissando with the knobs about 6 or 7.

It's a bit funny to see how some people tend to say that MOTM-format is dead, but when OP asks for must have modules most of them are originally MOTM-format modules...

MOTM is not dead (could be a great slogan :) )

CV-to-MIDI converter

... read that carefully ... a 5U/MU module that converts CV signals to MIDI signals (not the common MIDI to CV).

I want you to think about how many ways you could utilize many of those crazy-cool 5U modules you have to modulate any of your MIDI synths or other MIDI devices (such as FX units that have MIDI I/O and also have MIDI implementation charts).

The list of modules that could be used to play with your MIDI synths is as long as your leg!

** Sequencers.
** LFOs.
** Env Gens.
** Pitch Wheels/joysticks.
** Ribbon Controllers.
** Modulation wheels.
** S/H modules.
** Others?

At our disposal, we have MIDI/CV converters that bring velocity, aftertouch, note-on, note-pitch, MIDI mod wheels, MIDI pitch wheels, arpeggiators, sequencers, other?

But we have almost NO means of bringing the power and capability of our voltage controlled gear into our digital/MIDI gear.

There is no reason for this.

Think about using one of your modular LFOs to modulate the delay time of your favorite digital delay that has MIDI "CC" capability to control that delay time. Or using an Env Gen to do the same thing. Or using an analogue sequencer to do the same thing. Wow.

Think about using S/H to modulate the cutoff or VCO pitch of your favorite digital rompler or VA super synth.

The tech exists, it's not expensive, and there is no reason we should be denied this marriage. Think about a 5U/MU combination module that has MIDI-to-CV ... and ... CV-to-MIDI.

The power ...... the utter power! :eek: :woah:

(and we also need an aid module for the Dot Com Q114 ... the need is glaringly obvious .... yup, still bangin' that drum!)
:lol:

Possibly because hardware midi is an old protocol and doesn't allow for very fast modulation speeds. Slowly moving parameters aren't too bad but for fast changing parameters midi, and quite often the connected hardware, will struggle to keep up.

I'm not sure of what the maximum bandwidth is for a single 14 bit CC signal would be via one midi channel but I will check. I don't think it'll be much more than 200Hz though.

Honestly I am not one to say things are 'good' readily.
(you would be hard pressed to find one in muffs !)
(I think most stuff posted here and in muffs generally is pretty poor and mostly poor forumla stuff which no one would buy.)
but... just watching the start of 'You were never really here' and that piece would not seem out of place at all.. :)

Just checked with someone who knows about these sorts of things. He reckons it would be closer to 390Hz but that would be the ONLY thing you could send down the whole midi cable let alone in one channel. That pretty much rules out fast envelopes.

Note and gate information take less data to send which is why John could send such great arp work to the midi module. :tu:

Yep. Midi works great for instantaneous changes like stepped CVs or note on/off, and it works great for slowly changing continuous CV signals like slow LFOs, but it can't properly handle fast signals that are continuously changing, like a 400 hz sine wave. It results in severe stair stepping / 'zippering' artifacts getting imparted on the signal, or it just chokes.

There are some work-arounds for this, in limited applications - for example there are midi to CV converters (but not CV to midi as is being discussed here) like the Encore Expressionist that include their own portamento functions and LFO signals which get added to the control signal AFTER the midi bottleneck, and avoid zipper artifacts. But that's no help if you want to generate fast continuous CV signals in your analog modular and send them somewhere via midi.

What of pitch bend?

The last few weeks I've been on a quest to locate a CV-to-MIDI that will allow using (something like) a Dot Com pitch wheel to do pitch bends on digital/MIDI rack synths or the Nord Micro Modular. Roger Arrick makes all of these wonderful performance controllers ... it would be nice to be able to use them with digital/MIDI synths.

I've been corresponding with the eggheads at Kenton Electronics regarding that very subject. They (of course) offer their "Pro CV to MIDI" converter. They've said that the pitch wheel must be calibrated to 1v/octave output for their device to operate properly. Why is that? This simply baffles me. The wheel simply puts out voltage, it's up to the destination device (or the cv-to-midi converter) to turn that voltage into some sort of calibrated response.

If the wheel puts out (let's say) 2 volts when rolled all the way up, and that bends the note past the desired target pitch ... then don't roll it up as much with your hand! The player's hand is the "calibrator" (so to speak).

I've sent them links to the Dot Com Q181WP Datasheet for them to review (jsyk).

I just cannot seem to comprehend why "the wheel must be calibrated to 1v/octave" .... that just doesn't gonkulate in my head. How would one calibrate a wheel to 1v/octave in the first place? All it does is output voltage .... it's up to the device receiving that voltage to figure out what to do with it.

Meh .... it's probably just another instance of me not knowing my ass from a hole in the ground .... again.

RE; the Moon 552 ...

It might do ... but again, what of pitch bend?

[video][/video]

IN ANY CASE: I'm waiting on a shipment notification from a particular vendor on the Kenton Pro CV-to-MIDI box. Once they get their shipment in, I'll buy one immediately. I have several Dot Com "controllers" (not the wheel though) ... they all use the exact same output section ... the joystick, the foot control interface, the ribbons ... they all use the very same sub-panel with the very same controls and abilities. So while I don't have the wheel I want to use with my rack synths (the Q181WP) I can still test the concept using one of the other Dot Com controllers I have with the Kenton thingy.

I've also corresponded with that dude "Os" at Expert Sleepers regarding this pitch bend issue. He says he can write the script needed to modify one or two of his products to do this CV/MIDI pitchbend trick. He says that all it would take on the end user's part would be to download the custom firmware from him and upload that firmware into one of his devices (either the Disting Mk4 or the "General CV" module).

I'll point out that neither the Kenton converter nor the Expert Sleepers modules are in 5U format ... which is what this thread is about.

Right?

If you blasted out Pitch Wheel messages continuously, alternating positive and negative values, I get 520 Hz. That's two three-byte message, at 10 bits/byte (when the start and stop bits are included), dividing into the 31250 baud rate. For a CC, it takes two messages to send 14 bits of data, so 12 bytes per pair of messages, or 260 Hz. So your guess was close.
