Dualchord Expander

[kilgore]

I'm a bit confused about how to connect the expanders together.

So I now have my Dualchord, which is connected to the NSA port on the Nerdseq. If I want to connect the 2hp MIDI expander, that should be connected to the Dualchords second NSA port (not that other port on the Nerdseq?).

So I need a ribbon cable that goes from 12pin (MIDI Expander) to 14pin (Dualchord NSA).

Do I understand this correctly? Somehow I never realised how many different kinds of ribbon cables there are....I don't think I have a 12->14pin one!

No.

Midi got its own port -> 12 pin   -> 2hp, Midi-IO or Multi-IO (one of these)
NSA got it's own port ->14 pin   -> Trigger16, CV16, Dualchord, Video Expander (VEX)

There is never a 12 -> 14 pin adapter


Thank you! I had forgotten that the MIDI expander doesn't show up on the loading screen and thought I had it plugged in wrong.

Hi Thomas,
I would like to mount the DualChords a little bit further in my rack.
Is it OK to connect the expander to the NerdSeq with a longer 14pin cable, like 60 cm or even more ?

Officially I don’t support it but I know they are people who even made 1 meter cables and it works fine.
Take care that your cable is 100% OK. 
For the rest no guarantees for any side effects but I expect it’ll be fine.

Thank you, I've just ordered it at schneidersladen, they made a longer cable for me

Hello Thomas,

I would like to set up a pitch bend effect of +12 semitones to the oscilators 5-6-7-8 of the dualchord (while 1-2-3-4 remain unaffected).
This would be controlled by an I2C fader in the mapping screen.

I'm not sure there is a way to achieve that, but I guess it would require a good amount of coding in the mapping screen.

Your advice will be much appreciated.

Best,
Martin

You could do that with the detune but it is really more finetuning which doesn't cover 12 semitones. 
You can route the pitch through all octaves but that are not your music notes.

So if I understand correctly, the smart solution would be a "coarse tuning" function but it has not been impletented yet.

And the Pitch function would overrule the sequence of notes where I would like to rise up the pitch of theses notes.

Therefore, it's not possible to achieve this at the moment. Am I right ?
Would it be any chance so see a coarse tuning function implemented in the next firmware release ?

Cheers

Has anybody successfully mapped a usb host midi controller to play 4 notes live with the dual chord? I'm trying but can only play 1 note at a time. Using an Akai mpk mini 3 keyboard.

Is there a way to do an envelope, e.g. on the PWM? If I understood correctly, the LFO is a triangle shape and will run until it is stopped, otherwise that could be misused as a poor-mans envelope with linear shape.
It would be good to either have a few Envelopes for the shape to run through the waveform shape or on the PWM to shape sounds each time they get triggered. This would allow for sounds like typical roland type PWM basses (Envelope on the PWM) and Bassdrums etc. quite easily, even though a bassdrum could also be achieved by multiple notes and glide, to glide down. WAVE X velocity seems to be not in the list of modulation sources, e.g. for vibrato or if an envelope or one-shot LFO would available, this could do an in-module VCA, which may also be nice if driving a VCF a bit harder, so how much the VCF is driven could then be Envelope or LFO modulated easily.
A workaround could be to run the sequence at high resolution and edit “envelopes” into the sequence via FX values, though that would be a bit steppy and lots of editing.

Hello @thomas
I own the Nerdseq + CV16 + Trigger16 + Multi IO (and I thank you every day for this beauty)
I was wondering if there's a maximum number of expander modules that can be connected to the Nerdseq's NSA cable?
Secondly, during Black Friday (I admit, I was just trying to get the 25% discount, I'm ashamed...), I've been considering buying a Dual Chord from every angle.
After reading so much about the Dual Chord, I'm wondering why you made an additional module?
What was the technical or commercial constraint that prevented you from simply connecting it to outputs 7 and 8 (samples) and the trigger outputs to trigger 16?
