PlantsSystem-GranCho

video upload by plantssystem

"PlantsSystem – GranCho
Microscopic particles swell, resonate, and eventually melt into a single flow.
'GranCho' is an experimental soundtrack by PlantsSystem, combining elements of 'Granular' and 'Chorus'.
The sound, woven with granular modulation that distorts time and space and deeply enveloping harmonic processing, evokes a sense of floating between electronic and natural.
The interplay of stillness and movement, structure and decay, reveals a different expression with every listen. Digital yet organic—PlantsSystem enters a new sonic realm."

Control Synths from Your Phone: Piano Improv on Blade Runner Riff | iOS MIDI (Beta)

video upload by Cristián R. Villagra

"Live piano improvisation over synth riffs driven by my in-development iOS MIDI control app (no name yet). The app sends MIDI to my computer to play arpeggiators and tweak sound parameters in real time (filters, tone, mix, FX) using on-screen faders, knobs, XY pads, mini keyboards, and pitch bend.

Session routing (Kontakt):
• CH1: Noire Piano — played from Arturia KeyLab 88 Mk3
• CH2: Two synths — driven by the app’s Bass Arpeggiator (riff inspired by Vangelis’ Blade Runner theme)
• CH3: Lead synth — performed from the app’s mini keyboard
• CH4: Minimal electronic drums — driven by a second arpeggiator

Why this app? Many keyboards I use on stage have few (or zero) surface controls—sometimes not even pitch bend—so I built a mobile controller to unlock hands-on control: shape filters, automate movements, morph textures, balance layers, and keep playing fluidly. If this helps me, I know it can help other players too.

This video is a 6-minute+ live jam to show the workflow: arpeggiators keeping motion underneath while I improvise on piano and ride parameters on Page 2 of my scene (faders/knobs/XY). The app is still in development and I plan to release it as soon as possible.

If you’re into MIDI control, live keys, or sound design, tell me what you’d like this app to do next—your feedback will shape the release.

"Nice condition vintage analogue 'Symphonic Ensemble' polysynth / string synth / organ with excellent control over tremolo, ensemble and vibrato. With three outputs you can send different parts to different effects. The string volume pedal is also very effective at breathing life into sounds. There is a multi-pin output for a rotary speaker - not checked. But everything else was serviced in 2024. As usual, the massive wood-veneer endcheeks are not in perfect condition, but the control surface and keys are very good. Serial number 8632, switchable voltage, currently with a UK plug. These are solid machines: packing 18GBP."
