"This circuit board came in with one of the many Rhodes Chromas we have bought, restored and resold (we’re finishing another at the moment which we will list soon). It appears to be part of a rare chroma apple ii computer interface that allowed the apple ii computer with sequencing and patch editing software to control a Rhodes Chroma. The Rhodes Chroma website, which is probably the best vintage synth support website we’ve ever come across, has an article on this interface. You can find it by googling rhodes chroma apple computer card. It appears as though there were other components to this interface that we didn’t get with it (converter box, software and possibly more), and we don’t have an apple II computer, so we haven’t tested this item and are selling it as-is as a collectors item, or for parts to possibly get a full system working (with no guarantees)."

"Synthesizer module equivalent of the Roland Alpha Juno-1 and Alpha Juno-2 keyboards. This unit has been professionally refurbished, unlike most. The internal battery was replaced and what we believe to be the original factory patches were reloaded. All synthesizer parameters were systematically tested on all voices and are working as they should."

05.17.2025 Purcell for fun - First test with MDI and a few synths

video upload by batchas

"Video recording that I hadn't published from the first draft with the Minimoog and Juno 60, which I finally finished repairing. I'm so happy that everything is working again. I had already installed MIDI on the Minimoog, and I just installed it on the Juno 60 as well, since I reinstalled MIDI in the studio after a loooong hiatus. The 2500 is also MIDI-enabled with the addition of a clock division and MIDI-to-CV module in the matrix.
The track is far from finished! I had gotten used to the modular, where I turn it on, patch/play, and record. Now, of course, it's going to take more preparation to achieve what I have in mind.
To be continued...

En français : enregistrement vidéo que je n'avais pas publié du premier jet avec les Minimoog et Juno 60 que j'ai enfin fini de réparer. Trop content que tout remarche. J'avais déjà installé le MIDI sur le Minimoog et je viens de l'installer sur le Juno 60 aussi, vu que j'ai réinstallé le MIDI dans le studio après de loooongues années de pause. Le 2500 est aussi midifié avec le rajout dans la matrice d'un module clock division et MIDI-to-CV.
Le track est loin d'être fini ! Je m'étais habitué au modulaire ou j'allume, je patche/joue, j'enregistre. Là cela va évidemment demander quand même plus de préparation pour parvenir à ce que j'ai en tête.
À suivre..."

Formanta P432 + LELMIDIDRUM From UltraRare.SU

video upload by Futulyric

"The Formanta P432, a Soviet digital synthesizer, originally featured a very distinctive, authentic noise and could have been significantly improved if it had supported ADSR. This flaw has now been corrected; as a plugin, it sounds more interesting. The noise, however, remains, lending a distinctive vibe.
LEL MIDIDRUM is a digital drum module from the company of the same name, dating back to the Soviet era. No other surviving example is known, so its sound can only be heard here.
Also available as a plugin.
