Btw it was stuck in upgrade mode even after resetting modular UNTIL the firmware was successfully flashed. Seems dangerous to me, I could have been left with a bricked module if I hadn't persevered. Won't be changing the firmware again anytime soon!
Don't worry about locking the module, it is impossible by design.
The bootloader itself is never erased during upgrade.
So it is always possible to try again whatever the kind of failure during the upgrade process.

But how do you get it out of boot loader mode? Even after switching off modular it returned to same mode and I couldn't get it to boot to oscillator state.

At startup, the module checks if there is a valid firmware inside.
If not, it expects receiving one from the audio input.
An upgrade has to complete successfully for the module to restart in normal mode. It does it automatically.

Please send me an MP with the steps and feedback you observe so that I can help you.
Thank you.

1.20 succeded... via iphone and a mono cable...full volume !

i really like the lock on the tuner...so i can prepare my first live with a calibrated modular synth !

I locked the two oscillator together... with offset so i send sequence from my octatrack (via interface midi/cv) only on the first oscillator...the three outputs are mixed together and go to a LP filter ... big pads...(AE algorythm on the first oscillator, any on the second).

I offset the second oscillator to +1 octave... do you think it's better to put +3 semitons or +5 instead of +12 ?

So handy not accidentally knocking out tuning when I was trying to change the LFO rate :)

Thanks :D

All (digital) VCO should have lock on the tuner, it's really awful when you're in the middle of the fun and turn it by mistake. So yeah, well done :tu:

Findings in update 1.20

Post by Zentek » Tue Oct 31, 2017 4:24 am

You all, users of the Klavis Twin Waves, have enjoyed a string of firmware updates since the product introduction in Feb 2017.
With each addition, we have pushed the boundaries to the limit given the fixed computation power at hand.
Several of the new features were not planned initially and it happened that some brought unexpected side effects that we corrected. This is the case now with the update 1.20.
Some of you have reported problems using the Quad Saw algorithm simultaneously in both oscillators.
That specific algorithm was tweaked a few updates ago in order to improve its rendering at high frequency, hence taking more CPU cycles. Since then, we've added BZX FM and VCA, among others, also requiring their chunk of CPU power.
We now realize that to get back to rock-solid stability, we cannot play the Quad-Saw on both sides at once.
We are currently making a complete review of the processing charges to be sure everything else is OK.
The next update will not allow playing the Quad-Saw in the second oscillator. We hope that you understand that it is a small loss compared to all the additions gained over time.
Until this update is available, please keep in mind to not using the Quad-Saw twice.

Thank you to all who took the time reporting the issue.

[edit] Version 1.24 allows any algorithm to play in each oscillator :-) [/edit]

When setting the base note for the quantizer, what notes are 1 - 12?

I guess they are chromatic notes, A to G#?

These are chromatic but not specific notes; they are 1/12th volt steps going away from the base voltage detection.
This setting allows you transposing/positioning the quantizer itself, independently of the pitch generated (which you transpose with pots as needed).

FW 1.24 is out it seems :party:
Firmware 1.24 main additions

Any algorithm combination can be used freely in both oscillators
VCA in audio mode
Potentiometer locking capability to avoid detuning by mistake

Hi !
Something wrong with the download link ? Only 760ko and no wav file inside the zip ? Is it me ? :hmm:

What happened to v1.20? That's what I have installed. Seems like the only change from 1.20 to 1.24 is any algorithm combination can be used freely in both oscillators. I suppose this means that the complex algorithms can be used in Osc 2. 1.20 must be buggy. The 1.24 release notes:

- All algorithms are available in both ocillators
Improvements and fixes:
- VCA is back

See user Manual V1.5 for details

Works fine.. size is completely normal for a FW. Use another unpacker..

Yep, this is why it was removed and we reverted to 1.16
Sorry for the trouble.
1.24 is now replacing all.

Someone got some scope shots of it flipping the wave when going through zero? I really enjoy the sound but does it through zero fm indeed? I am not sure what I hear... :despair:

Yes, it does. Although it's not at 0V at the FM input but at 2.3V (where I get a 8 sec cycle time). See attached screenshot from my scope.

[edit] The 2.5V for 0Hz output makes sense as with no cable in the FM input you would get 0Hz = DC. The module does the same thru zero at -2.5V. At +5V or -5V at the FM input you get the same freq as with 0V or no cable.

Thanks for coming with the explanation 8-)
You were faster than me !
It works exactly as you describe. :tu:

I join the image of a trace of a sine FM-modulated with an LFO triangle.
The slope of the triangle wave gives enough time to see the audio frequency decrease, then stop to finally restart mirrored.

A second example is with the quad-saw also modulated with an LFO triangle.
