SynthFest France 2025: Cyma Forma ALT soundscape synth is almost finished; the developers showcased the production unit with major melodic feature update.
Last year at Superbooth, the French company Cyma Forma premiered the ALT, a 5-voice/oscillator pin-matrix analog Synthesizer. Almost simultaneously, the Kickstarter campaign launched, and the synth was successfully funded.
A lot has happened between Superbooth 24 and now. The ALT has been expanded in many areas and is almost finished. At SynthFest France 2024 last weekend, developers Vincent and Vincent showed off the latest version that will go into production very soon.
Cyma Forma ALT
There are many changes. First, the oscillators were redesigned. Instead of VCOs, they now have DCOs. They’re still analog but digitally controlled to enable new features and improvements.
In addition to improved frequency accuracy, the DCO implementation opened the door for a new built-in harmonic quantizer. It allows you to choose scales and play melodies with the sliders or quantized pitch modulation. The free (linear pitch) option for drones is still available.
The new harmonic quantizers come with scale presets and the option to use custom scales. They also have accurate root note selection and a detune setting per oscillator.
Then, Cyma Forma added a new LFO range switch for switching between low and high, expanding the oscillators’ FM synthesis options.
The original design featured a characterful MS-20-inspired stereo analog filter. The final circuit features a second stereo filter that cascades the first one, extending the filtering capabilities with bandpass, notch, 4-pole lowpass, or 2-pole highpass.
ALT also comes with a new expanded input feature set. As a reminder, the external signal consists of two signals: the external input that goes into the envelope follower (now with attack control), which can be used as a modulation source, and the mic signal.
The new circuit allows you to route the external input into the audio mix out with a pre/post Alter section switch. This new functionality turns Cyma Forma ALT into an instrument effect processor. The input socket also has an invert switch.
The Cyma Forma developers also added new destinations to the pin-matrix modulation system: random frequency, cutoff for the second filter, and random offset. The random modulator also now hosts a glide switch.
They added two performance-oriented momentary push buttons for instant cutoff filter modulation, using the mic and noise as permanent modulation sources.
Finally, MIDI support is also now onboard over DIN/TRS and US, which is great for the voice split mode. The latter splits the five voices on your keyboard.
Second Impression
The original design was somewhat limited to drones. This revised version offers significantly more options for routing and interacting with sound. Nice to see that the developers have taken a lot of the feedback into account.
I had the chance to check out the production version last weekend at SynthFest France. It’s a very hands-on synth that thrives on live exploration and experimentation. There are no presets; the sound you make is in your hands. A very unique synth with more than a drone fun factor.
The Kickstarter units will start shipping in July/August 2025. ALT goes in the regular in September 2025 and will be exclusively available in their webshop for the first year. Later, they will expand the sales to retailers. The official price is TBA, but it will be around 1000€.
Update From May 22, 2024
The Cyma Forma ALT pin-matrix analog Synthesizer celebrated its premiere at Superbooth 24. Now, it is available for pledge on Kickstarter.
The Kickstarter price is 990€. Production will start at the end of the year, and shipping will be in February 2025.

Cyma Forma, a new French company, has been teasing the ALT Synthesizer since mid-April. It’s a desktop analog pin matrix Synthesizer with a unique fader concept. They will showcase it to the audience at Superbooth 24.
Today, they published the full demo, which provides an overview of what is possible with ALT.
I watched the whole demo, and I can say that this is exactly my taste in synthesizers. Many points make it very tempting and exciting.
Firstly, the design and layout. Lots of controls, no menu diving, and everything is hands-on. You grab a slider, and something happens. Yes, the slider is something different, and I like to see them on a desktop instead of the classic knobs.
Modulation using a pin matrix is also a neat decision. This removes some of the complexity and makes it very playful, a bit like sinking ships for modulation.
It stimulates exploration, and so does the experimental spirit. By setting pins and pushing and turning parameters, you explore the instrument in a very analog way. More enjoyable than scrolling through presets.
I also like that you can use the synth as a drone/noise machine and play it with a MIDI keyboard. This makes it interesting for a broad synth audience.
The tests will reveal how wide and versatile ALT’s tonal sound spectrum is. However, the linked demo gives a good impression of where the journey is leading.
What is certain is that you can see and explore the ALT Synthesizer at the Cyma Forma booth (H210) at Superbooth 24. And the synth will be available for pre-order at Kickstarter right after SB 24 on May 22nd, 2024.

Ok, ok, now I know that you like knobs and faders on your keyboards and synths. What came from synth news yesterday from France was probably less for you. Here’s a second synth news chance from France. I’m sure more people will like this because it’s classic synth nerd stuff.
I noticed Cyma Forma on social media, a new Paris-based company that is currently developing its first Synthesizer. ALT is the name of its fruit, and it will be coming to Kickstarter in May.
Cyma Forma ALT
ALT is a new, intriguing analog Synthesizer. The instrument triggers my curiosity primarily through its different layout. Many sliders are placed in two rows, which is rarely seen in modern synths. There are also knobs on the interface.
According to French developers, ALT features five voices, each with different waveform shaping possibilities. The five voices are not grouped in two or three oscillator blocks, like in usual synths. In ALT instead, you have an oscillator for each voice, giving you five independent oscillators.
Each oscillator offers frequency and amplitude control on sliders, and waveshape, and stereo pan controls for spatial sounds. Cyma Forma says they provide a harmonic quantizer with scale support. Once chosen, you can play melodies with the faders, or with quantized pitch modulation. I wonder if you can play the five voices simultaneously like a traditional polyphonic synth.
The signals then travel into a stereo filter inspired by the legendary, aggressive-sounding Korg MS-20, which has lowpass and highpass settings. The parameters cutoff and resonance are also implemented with sliders. From here, it goes into a stereo delay. Cyma Forma promises it has a wild character with infinite feedback.
Pin-Matrix Modulation
A special feature and highlight of the synth is the built-in pin matrix. Synths that immediately come to mind include the recent Analogue Solutions Ample, EMS VCS3, Maplin 5600S, and more. It’s not confirmed, but from the available photos, it looks like the pin matrix is analog, not digital, like the Erica Synths Syntrx.
This is used to connect modulation sources with destinations. In this ALT synth, you can work with four adjustable modulation sources that can be patched into up to 17 destinations. On the mod sources side, you get two LFOs, a random step generator, and an envelope follower. Classic envelopes seem missing, suggesting that this is more of a drone synth than a classic polyphonic synth.
Further, ALT features light and sound sensors that can interact with the synth engine.
First Impression
Drones or classic synth, that is the question I ask myself. If it can do both that would be very exciting. The design arouses curiosity. I’m looking forward to the first demos and the price on Kickstarter.
Cyma Forma ALT’s release date and price are TBA. You can support the development by pre-ordering it through the Kickstarter campaign starting on May 22nd, 2024.

I like to see and hear it in action.
Nice!
I really like the look / sound of this.
Plus, it would fit in my setup nicely.
I just hope it’s not too expensive.
£500-600 or less and I’m in.
I really love the sound of this – the fact it has both CV and MIDI inputs is really good. I hope they have a future video showing how the modulations integrate with external control (not that external controls it, but say if I set-up a random element on pitch does MIDI pitch override it or play with it in some manner, like become a way to change the root).
It needs more scales (user-programmable tuning systems and scales and this thing would kill).
I’ve been part of the very early birds candidates. I did not manage to get one of the early or super early as it went so fast. The project was funded in only 6 minutes! Well done Vincent & Vincent.
Full plexiglass cover for a 1000,- unit? That’s… Ugh. That stuff seems to scratch by itself when you aren’t looking. Cleaning tips usually mention “don’t touch it!”
ha, I thought I was the only weirdo to have the same thought
Yeah, plexiglass is not great stuff.
Not only that, the knobs are 3D printed!
Everything I’ve seen / felt that is 3D printed is not a very pleasant tactile experience. It looks and feels homemade. Not really an issue on cheap or DIY synth, but 3D printed knobs on a £900 piece of gear is ridiculous.
I was interested in this at first, now I’m not even remotely interested.
I tried also via my mobile phone but it was all the time rejected. Crazy fast people and strong internet connections.
I’m curious to see if it will be in the stores at some point and what the price will be.
