"First patch testing the MIDI-to-CV module I made for the matrix. One sequence running.
First time BTW that I push the filter resonance so far.
Around 3:30 I am playing with the velocity."
Switching between 3 signals via 1050:
1- 1004-P Fmed by 1004-T and sent to Filter 1006.
2- Kesako 'Player' external module (here as standalone, though made originally for Buchla modular).
3 - 1004-P rectangle waveform.

"Voilà un premier test du Trigger Bus que j'ai conçu et fabriqué pour compléter le séquenceur 1027 de mon MOS-LAB 2500 . Ici, les deux bus A et B activent séparément des ADSR qui l'une passe un bruit blanc (cymbale) et l'autre le "PING" du 1047 (bass drum). Here a brief test of the Trigger Bus 1027 extension I designed and built for my MOS-LAB 2500. There bus A and B are connected to two indépendant ADSR that drive a VCA with white noise (Hat) and the 1047 resonant filter (Bass drum)"

This is a new custom system. New modules and new modulation matrix sliders on top and bottom. Rumor is that MOS-LAB not be selling systems with the modulation matrix, so modules only? If so, will they have patch points? These don't. All patching is done with the matrix switches you see on the top and bottom rows in these images. You can find additional posts featuring the ARP 2500 here.
You might remember mention of MOS-LAB creating a 2500 clone back in July here. An ARP 1026 Preset/Voltage Module Clone recently came up for sale. Not sure if it was from MOS-LAB though. As of this post there is no info on the MOS-LAB website.
"I rearranged the studio and am testing different things with diverse machines around the 2500 and a simple sequence. There's IMO a promising potential, but it would require way more time to invest, than the one hour I spend on a session to make a serious track. I usually concentrate on one modular system, cause it's more direct, plug'n'play fun, perfect for short 30 minutes sessions in the studio. But I've been thinking for a long time about having again the drum machines in the game, also some rack synths I like. Means connecting again MIDI and so on. I hesitated a lot, cause the last thing I want to do is spend time on programming! But I have to admit that I'm easely bored with the repetitive 16 steps sequences on the modulars (or 32 or 64). Time will tell if it was a good idea to take out the Buchla system to make space for the beat machines & effects corner.
The first synth we hear (4 bass notes repeating) is a Oberheim Matrix 1000. Then comes the Ace Tone FR-2 drum machine. Then the 2500. And after the Waldorf Q (fast sequence, staccato)."
"I made different patches in the same sessions, also checking how the 2500 filter does sound with diverse waveforms.
In retrospect I think a simple beat on top wouldn't have spoiled anything, at the contrary."
Due to unforeseen circumstances I’m selling my brand new( just several weeks old) hand made Mos Lab system. Price reflects what I paid for it minus the shipping cost and import duties. Not looking to make a profit on this.
Only 30 cabinets were made and these are the last two."
"I recorded on 2 tracks in the DAW. Track 1 is the output of filter 2 and track 2 is output of filter 1 (hihat sound made with noise).
I don't have a multiplier in the 2500. So to multiply the clock of the hihat I simply copied the hihat track in the DAW afterwards and shifted it a bit to make it a double of the main clock.
I send the output of the sequencer to a quantizer before going back into the matrix to control the CV of the 3 oscillators."
"Une séquence très simple pour tester un quantizer que je pense adopter.
Je n'ai eu que des problèmes techniques depuis que j'ai acheté des modules et un rack Series 500. Ça a commencé avec le boitier 500 qui ne passait même pas dans le rack et ça a continué module après module (même avec du neuf qui ne fonctionnait pas et que j'ai du échanger), jusqu'au ground loop hier sur les entrée DI qui empêche tout ! Bref j'aurais mieux fait de m'en tenir à mon setup habituel, plutôt que de me lancer dans le API 500. Alors afin de me calmer, je me suis mis sur le 2500 et j'en ai profité pour essayer un quantizer (le Shakmat Bard Quartet) avec une séquence toute simple. J'ai commencé la session avec un tempo bien rapide ( • 02.07.2025 Mos-Lab & Scrotum Lab - Th... ) et puis la séquence et le tempo se sont adoucis jusqu'à cette fin de session qui aurait pu encore continuer, continuer, continuer..."

"A very simple sequence to test a quantizer that I think I will adopt.
I have had nothing but technical problems since I bought modules and a Series 500 rack. It started with the 500 box that did not even fit in the rack and it continued module after module (even with new ones that did not work and that I had to exchange), until the ground loop yesterday on the DI inputs that prevented everything! In short, I would have done better to stick to my usual setup, rather than launching into the API 500. So in order to calm down, I switched to the 2500 and took the opportunity to try a quantizer (the Shakmat Bard Quartet) with a very simple sequence. I started the session with a very fast tempo ( • 02.07.2025 Mos-Lab & Scrotum Lab - Th... ) and then the sequence and the tempo softened until this end of the session which could have continued, continued, continued..."

"Une vidéo en français comme état des lieux relatif à la matrice que j'ai construite pour les modules du Mos-lab 2500.
I checked the french text generated automatically by youtube and did some corrections, so the english translation is available and not too bad."
"Therapeutic time with today's version of yesterday's patch. This time with only Mos-Lab 2500 and Oberheim Matrix 1000 active tracks and the other synths are muted. With additional delay/reverb from Audiothingies Doctor A.
Recorded in one take, so I don't spend more than one hour per session."
