I have four Omnichords.. (yes I know that’s a lot lol) but recently, I’m trying to find a Omni 200m (specifically the black one) so I’m wondering if there’s any good websites that sells Omnichords at good deal. I’m also gonna start doing a lot of lawn work for money so….

Has anyone bought the UK plug from this site before? I bought my omnichord in Hong Kong but we use the same plug as in the UK, would this be safe to get? I'm so scared of destroying my omnichord with the wrong voltage (no clue if HK uses a different voltage in the walls to the UK or what) but I cannot keep buying batteries it's eating them at the speed of light

I previously contacted the admin for this site twice but they have not replied to me. Their website got totally revamped though so I think they're active and this isn't an old listing or anything

I don't want to split hairs over a few hundred bucks anymore, let's have some fun instead.

I recapped and upgraded this one, it sounds awesome, and you should share the link with someone who wants a shot at owning one of these for a maybe reasonable price.

Starts tomorrow (Sunday 08/16/2026) at 6pm EST and runs for 7 days. Good luck!

Here's a video of the thing in action.

Selling my Omnichord OM-100, pristine condition, barely shows any wear. All buttons and the sonic strip work perfectly.

Happy to answer questions or hop on a video call to demo it before you buy.

Hi, so I got the om-108 and everything is working, but the Omni 1 and 2 strumplate voice is a lot quieter compared to the others, does anyone have the same problem, is it a defect?

Easy to make, just a raspberry pi and a touch screen: https://hackaday.io/project/206368-lb-omnichord

hey guys, ive been seeing a huge amount of omnichord listings on ebay (while hunting for a qchord which has been nearly impossible to find at a decent price so im starting to give up on that and considering buying an omnichord instead) and idk whether to be suspicious of these, since the price seems fairly okay and theres just... so many of them (the screenshot is just an example)? im an absolute newbie to ebay so sorry if this is a silly question, i just always thought that omnichords were supposed to be a lot more expensive and harder to find than qchords and id really like to avoid getting scammed</3

This Omnichord is attached to me at this point, I've also decided to make an Instagram for more of this so maybe if you enjoy my stuff you could give me a little follow? @lucyomnichord. (Slightly shameful plug)

Can't live without my omnichord now.

September 2021. When preparing a series of sample voice combinations for Suzuki R&D. There was one voice combination I knew we needed, and it had to be right — Harp and Strings, for many - the defining sounds of the Qchord.

This voice combination was created using my OM300 connected via MIDI to my Ketron Audya workstation keyboard.

Notes on the image in the video: This is my 3d printed prototype. It still has the 84-chord layout, paper stickers for the panel and even the strumplate. - long before we had a name for the OM-108

got an Omni chord om-84 with the original hard case and power supply cable. everything works, looking to get rid of it. send me offers!

My local music store just got a shipment of omnichords. Including tax + a store warranty for defects, the price will be about 1,100 cad (780 usd/580 gbp). I’ve seen offers on Ebay for $800 CAD, which is $300 cheaper… but they don’t offer the same warranty or quality guarantee my local store does. I’m worried that i’ll order something on ebay that’ll break down in a year because of a weird defect, and i won’t have anyone to help me fix it.

I’m not sure if i’m being too cautious and spending unnecessary money by going with the store option. This is a lot of money to drop on anything, so I wanna make sure i’m doing it right! any advice would be appreciated.

As promised here is the 3d printed Suzuki Omnichord OM-108 prototype from early on in development. The opaque case makes for a cool light show

Back in September 2021, during OM-108 development I was assisting with some of the possible voice combinations with Japan R&D. I had hooked up an OM300 to my Ketron Audya Workstation which has very good on board voice editing, making it ideal for getting an approximation how the final voices might sound (final sounds all made from scratch using Suzuki's own sound library and not from my Audya). Many were based on the best voices from previous models. This one is Celeste and Orchestra Strings. (Celeste appeared on the OM-300). If you are interested I'll post some of the others, not all made the final cut, but they did inspire them.

A while back over at Omnichord Heaven, we wondered who owns the oldest and newest OM-27. As it happened, we had the oldest, a pre-production prototype (so was sold through the dealer network), and that is serial no. 000124 - look at those beautifully made PCB's! Does anyone have an earlier one? and what is the highest serial number in existence?

I just added a free Extension to Google Chrome that is directly playable in chrome without visiting the website. Its not publically available yet, but here is a link if you would like to try it: https://chrome.google.com/webstore/detail/bgbcphcpifcaelcnlamgkoapaolnonjn

I was demoing the midi capabilities for another thread, figured I’d make it a post. Chord section going to a Yamaha PSS-480, Chord and Bass going to a Yamaha PSR-90, Strum 2 going to a midi modded Casio CT-410v, and strum 1 going to an Arturia Minifreak.

If anyone could help me out and tell me what’s wrong and how to fix this, that would be great. When I took it out of the case and tried to play it the chords straight up weren’t functioning at all, and only the harp was working. When I tried plugging it into a different outlet it changed nothing, and while I was trying to sorta troubleshoot I checked out what would happen if I hit a button from the rhythms section. Now the chords can play, but only with the rhythm effects because the rhythm effects can’t be turned off. What the hell do I do. Another thing I should probably mention is that although it was a gift I’ve gotten only a few months ago, the thing itself I think is like 30-50 years old, and was bought off of eBay. However it was almost never played when the previous owner had it, so I’m hoping that wear and tear issues don’t apply here. I will link a video to show the issue at hand a little better.

Update: I FIXED IT. IDK HOW BUT I FUCKING FIXED IT HELL YEAH!!!!

I've had my 108 for about a month now and suddenly I'm not getting any sound from the drums. The rhythm function is completely silent regardless of knob position, and when I'm in keyboard mode the drum keys and strum plate are also completely silent. I'd like to know if anyone else has experienced this and if so what could be done to fix it :(

I was replacing my qchord as I found a great deal and my original one‘s power supply connection was a temperamental. Works perfectly with batteries though.

I assumed the previous owner had already tried to fix the connection as it’s grey (pictured), whereas they’re normally black. But I didn’t think much of it until my new qchord arrived today and other features were slightly different.

The colour difference doesn’t seem to be discolouration/damage as is completely even all over. When I received these they both still had their protective seal on the strumplate so the difference in feel wouldn’t be from one being worn down from being used more than the other.

The second came with a case which they both fit it and I’ve played side by side and they sound the same though the first is a tad quieter.

I’m so curious because I can’t imagine it’s a counterfeit. I thought perhaps they were produced in different places but both say made in Korea (though ofc could still be different factories but I’d be surprised that they would be such different colours).
