First post: big ask: any chance of Hz/v on Hapax?

Hapax

Hello there,

I’m new to Hapax and Squarp in general. I picked up a Korg MS-20 original and I reckon the Hapax would be a great sequencer for it, if it could do Hz/v. I know there are work-around’s for the MS-20 using frequency to voltage, however its not very reliable.
Maybe its there already and I just don’t know how to set it up?

Cheers!,

Hey, same problem here, I have tried to send cv values from Hapax to my old ms-20, but in spite some notes are tunned most of them are not. I’ve tried both options 1 and 1.2 v. Any ideas?

Thanks!

Well, the Hz/V scaling on the Pyramid never worked properly, so I can’t imagine it translating well to Hapax.

I also have an old MS-20, and I have been told that it should be in the next version, 1.20.

ohhh I can´t wait for it :slight_smile:

This is great to hear. I’ve been using my old Elektron analog four to sequence it via CV. W/ the hapax, I’ve gone back to using midi for the time being, but I miss the expressiveness/tightness that CV offers.

Hello again,

since the great new update (2.0) now there is the possibility to calibrate the 4 cv outputs, but the calibration is only over the C notes, thus the other notes of the scale still are out of tune in my old MS 20. Or am I missing something?

Thanks,
all the best.

Is hertz per volt an option yet with the Hapax?
I’m very interested in replacing my Deluge with the Hapax, but I have a couple of Yamaha CS synthesizers that need hertz cv!

I assume it’s OK to share information sent to me by Squarp.
They’ve said that hertz per volt is in the works, but that S-Trig and gate signal >5v are not possible on the hardware.

Hey everyone, I was circling back on this post, and just wanted to say that Hz/V has been enabled in the 2.10 Hapax OS.
It should work fine, as it’s been tested by a few of the happy owners of MS20, but I’d be glad to have a few more confirmations on this.
Cheers!

Hello

Happy Hapax user here, and happy owner of a MS20.
I just tried to use HAPAX today to control my MS20. It kinda works, but the tessiture ( scale amplitude) is not that great yet : it tracks Ok on 2 octaves only, but above or below that, it goes out of tune rather quickly. It seems that the range is too narrow.

For instance :

  • If I hit a middle C, and tune the MS20 accordingly.
  • Then I play the upper C one octave up : it’s fine;
  • then the upper C one octave above, it plays a B.
  • If I try the lower C (one octave below the original one), it plays a C#

Is there any way to fine-tune the range so that we could have a 4 octaves range?

(For what it’s worth, and in comparison, CVOCDmanages to track 4 octaves and stay in tune)

I encountered the same issue when it first was added, and unfortunately I believe this is a hardware limitation on the Hapax.

Here is the reply I had from Squarp:

I think it’s a problem with the limited output voltage of Hapax (-5V to 5V).

On the internet, I can’t find what range the MS20 is supposed to get (for example 0V to 10V) and what range your Kenton is outputting when in Hz/V mode. But I think its range may be larger and more adapted to the MS20.

Below you can see the Hermod+ specification for Hz/V (soon to be added in the Hapax user manual) :

So if the MS20 doesn’t accept negative voltages, the range you can finally use with Hapax is something like F7 to F8
