My friend who built the Syncussion for me also built me a MIDI cable for it... but i'm using it with a 1/8" to 5-pin MIDI adaptor that came with my Korg SQ-1 sequencer. I'm wondering if that adaptor is the problem here...

Can anyone give me a link to a 1/8" to MIDI adaptor that they know is wired to work with the syncussion's midi?

I'll admit i'm a MIDI-DUMMY...
The first page on the MIDI Reference has the pin outs + its saying :
(This wiring is the same as the adapters provided with the Arturia Beatstep)

edit: never mind! Think i found the right one.

The midi doc says "Beatstep" but it's actually the Beatstep PRO

That's great to know, surely in for some more Syncussion action. :guinness:

So I've got a weird problem with my latest builds hmmm.....

Everything seems functional except for the fact that the whole machine sounds a few octaves too low. So only the top bit of the pitch slider results in a tone you can hear, the rest is too low in pitch to hear. Got this problem with the latest 2 kits, I've narrowed it down to a problem in the voice boards as I had a working unit and putting that voice board on the weird-acting ones' control boards worked out. Anyone recognize this behaviour?

- Tried swapping out 4096's
- Tried new headers between the boards
- Went over all the SMD pads
This sounds like a component misplace. If it's happened to two builds there's a chance you've re-bagged some resistors in the wrong bag at some point. I'd start by checking all resistor values against the working unit. (4k7 and 47k are prone to getting mixed up wink Colour codes are your friend thumbs up

Went over all components comparing to a working voice board, can't find any mistakes.
Is there a specific place I should start looking at in the schematics? Pitch for both voices is way too low, with only the top part of the tune sliders resulting in anything at all. Hoping someone recognizes this issue, going crazy over this. :despair:

if anyone has a spare kit let me know!

I have a THC version I love but want midi for live so I can bring one less sequencer

Just out of curiosity.. why are there two diferent sets of 100uF electrolytic caps? The axials are 1,90 euro, the radials 0,20..

Thanks, I'll maybe try this on my other clone

please can you tell me how to add this pi filter on the THC version ?
thank you!

I finished mine quite some time ago...
Now in using it i noticed there is something wrong with it.

In modes B-E the sound disappears when the tune fader is below 50%.
It seems the OSC1 goes sub Audio frequency then

I resolderede all the ground solder pads and checked all components.
Anywhere else to look?

I have a complete Mouser BOM for the SY-1M left. Will give a discount of 10%. PM me if you're interested...

Did you manage to fix this? Seems very similar to what i have on my build

Got tired of troubleshooting and ended up selling the kits as-is for cheap. Sorry, hope you figure it out!

Hey guys

I'm wondering if I might be able to get some suggestions on what you think might be wrong with my PsyCo X Syncussion SY-1M. I did not build it, but had a friend put it together. I'm also not super knowledgable with building -- but I'm hoping to gather some ideas for what I might look into to try and narrow down what to focus on... I've talked with Simon at PsyCo X who has been very helpful, but without mailing him the unit overseas, it's hard for him to diagnose problems... Maybe someone here might have some ideas...

I'm having two problems that have been occurring since it was built....

#1: I'm getting noise/hiss coming from the unit. You can even hear it when it is powered on, even when the unit is not being triggered, i'm getting some strange noise coming out that seems to change depending on where the sliders are positioned. Seems to become quietest when the sliders are at around 80%. The noise level seems too loud to be normal to me... I've tried multiple different power supplies and the problem stays the same...
Here is a video showing this...


#2: I'm intermittently getting audio popping/cutting out when touching the top volume slider. I asked the builder to replace the volume sliders because of this and the popping has still continued. Could this be related to something else, or do you think I somehow got defective sliders twice in a row?
Just lightly touching the slider will make it the audio pop and crack...
Here is a video showing this:


I'm just hoping to gather some ideas and info to pass along to my builder to hopefully give him some areas to focus on whenever I can talk him into looking at this again.

Hey, can anybody link me to a power supply for this? Also, anybody have a link to some knobs?

Anybody else got some dodgy output volume pots? Looking into a build here with a partially functional Ch. 1 slider and a nearly dead Ch. 2. Yes, soldering is clean. I have spares on hand so first step is to swap them out but I'm curious if I'm the only one. The previous half dozen I've built have not been afflicted by this.

I just encountered an interesting, strange and as of yet unexplainable phenomenon with my SY-1M:

I had set up a few sequences in a Beatstep Pro as well as a, let's say, bongo-to-marimba kind of sound on the SY-1M. When connecting the BSP to the SY-1M via CV/Gate, all that comes out is a really quiet 'click' or 'bonk'.

Everything works as expected when I use a Korg SQ-1 instead ofg the BSP. And playing the sequences from the BSP on my TTSH also works as expected (I used the same cables all the time to make sure they're not the cause). So I'm 100 % certain all four devices (BSP, SQ-1, SY-1M and TTSH) including the cables are fully functional and not faulty in any way. It's only the combination of BSP and SY-1M that behaves weird.

I have no idea why the BSP and the SY-1M won't work together. Trying to trigger a sound via the square pads on the BSP also produces this quiet 'click' or 'bonk' sound. When the CV/pitch cable between BSP and SY-1M is connected, manually triggering the SY-1M also leads to 'click'-'bonk'. I can, however, manually trigger the Syncussion just as usual when no cables or only the gate/trigger cable are/is connected.

Any ideas? "Just use the SQ-1 then" is not an option in this case since the sequences (9 sequences with 48 steps each) are too long for the SQ-1. If it actually turns out the BSP and the SY-1M don't like each other I'll have to (and of course can) set up a similar sound on one of my other synths, but I really wanted to use the SY-1M in this case.

what are the voltages on the CV and gate? Is the gate inverted?

I tried various CVs from low to high pitch (~ between 1 and 5V), and the BSP gate voltage is generally set to 10V - but I can of course double check. Gate isn't inverted.
As I said - the Syncussion works perfectly with the Korg SQ-1, and the BSP works perfectly with the TTSH (as well as with the MFOS Ultimate, and others). That made me think the four devices in question should all be compatible with each other :despair: .

But I'll also try using MIDI and see if that works. According to the SY-1M docs, the TRS configuration is "Arturia style", not "Korg style" so I won't even need to solder an adapter cable.

Thanks anyway for your input!

Yep. Works as it should. Just recorded the sequences in question :tu: .
Note to myself: Just use MIDI when sequencing the SY-1M with the BSP, and everything will be fine. Luckily I built the Syncussion version that has MIDI included :mrgreen: :tu: .

Case closed for now, though I'd still be interested in why CV/Gate isn't working from the BSP in this case.

if you have a meter or better yet a scope, it would be worth comparing whats coming out of the BSP compared to what works

Yep... might try that sometine (I have an o-scope of course - my SDIYing would be impossible without one :)). For the time being, I'll just stick with what works and use MIDI if I want longer patterns or melodies.

Quoting a popular TV show/character: 's all good, man ;)!

I think I trimmed my male headers a little too much.
I try @Mouser but can't find the one's with the same lenght side.
Anyone know where to find these 22 pin, press fit, breakaway header strips ? (Those included in the kit)
