"Audio + Video by G-Storm Electro c. 2025

Today I am going to service a Roland RS-09 having some issues. I'm going to
address the tactile button actuator assembly
troubleshooting the dead button panel circuit
address some metal panel rust
replace some felt dust filters for fader pots
deal with the rickety plastic rivet fasteners for the front panel.
Lots of fun stuff.

Yamaha Montage M & Genos 2 | SynthFest 2025

Click CC on the bottom of the player for subtitles.

"La nouvelle série Montage M de Yamaha repousse encore plus loin les limites. Les synthèses FM-X et AWM2 se voient complétées par un moteur de synthèse complet AN-X, simulant les circuits analogiques et reproduisant leurs imperfections si musicales. Des écrans contextuels apparaissent à gauche du panneau, et le M8X signe le grand retour chez Yamaha du Polyphonic Aftertouch, longtemps après le CS80. Des commandes supplémentaires et une librairie sonores étendues en font un clavier ultime."

Googlish:

"Yamaha's new Montage M series pushes the boundaries even further. FM-X and AWM2 synthesis are complemented by a full-featured AN-X synthesis engine, simulating analog circuits and reproducing their musical imperfections. Contextual displays appear on the left side of the panel, and the M8X marks Yamaha's return to Polyphonic Aftertouch, long after the CS80. Additional controls and an extensive sound library make this the ultimate keyboard."

"The sampler has been completely refurbished. The casing has been painted black. All tact switches have been replaced, the old LCD with a new LED and pad sensors. Additionally, I have installed the Gotek FDD emulator (32GB Sandisk pendrive included), the latest Vimana 3.15B OS, max RAM memory and multivoltage power supply. This means that it does not need step up or step down converters to work! The voltage switches automatically depending on the place in the world. It accepts AC voltage from 65 to 265V. This is probably the only such version in the world. I was going to replace the LCD window, as it has a few scratches, but I'll leave that to the new owner. The glass is available on eBay, and replacement is easy (double-sided tape). Insured shipment."

"Akai S-612 (US model, including voltage converter). It was serviced just last year (faders were cleaned) and works perfectly. It has two additional special features:

1. The XD-280 Disk Emulator, which can be used to run an HxC Gotek floppy disk emulator (this one with an OLED and rotary encoder). A USB stick with a sound library is included.

2. The FDM Filter Defeat Module. The blue button on the front left next to the display allows you to deactivate the anti-aliasing filter in various ways. This can make the S-612 sound like an E-MU SP1200, with a very crunchy sound."

Teenage Engineering K.O. II KNOCK OUT - How about a FMT and start from scratch?

video upload by Cinematic Laboratory

"The Teenage Engineering is an affordable sampler with 64 MB of memory. In this video I'd like to focus on sampling found sounds, noise boxes and small modular setups. I'll start by formatting the internal memory (FMT) which is a great way to really get to know the KO II without going through all features first. This is not a tutorial. If you want to learn how it works, please visit ‪@SONWU‬ and check out his series which also includes the firmware update.

It's a great machine to stay away from the DAW but also a good 'brain' for sequencing external gear with MIDI, and for turning modular mono sounds into pads and textures. Another cool trick is to sample a chord under each pad, so you can play all kinds of complicated chord progressions with one finger."
