ReleaseDateWhat's newFiles
18 (current)October 21, 2026A detailed sweep of the orchestra against real instruments' acoustics. The bassoon no longer plays an octave too high, and the oboe no longer jumps octaves or chokes when played hard. Brass now speaks with a tongued attack, gets brighter the harder it is played (new BLARE and BELL controls), plays in tune and stops cleanly. Strings speak sooner and stay in tune to the top of the violin. The clarinet has real even harmonics (new EVENS control), the woodwinds have real breath, and the harp is in tune to its top string. The grand piano is warmer, voiced after a Steinway D. New IMPERIAL GRAND (Bösendorfer voicing) and STUDIO GRAND (Yamaha C5 voicing). Windows · Linux
17October 19, 2026Fix: a stereo module (reverb, delay, ROOM, mixer) patched into the OUTPUT's LEFT jack alone played in mono, because its right channel was dropped. It now stays in stereo. A sound patched into RIGHT alone now plays in both speakers instead of one. Windows · Linux
16October 19, 2026New patch HI-TECH ROCK JAM, built for velocity. Soft notes are clean, round and slide up into pitch. Dig in for drive, bite and FM growl, and accents add a pinch-harmonic squeal. Windows · Linux
15October 19, 2026Fix: reopening a DAW project showed the patch as UNTITLED. The project now remembers which patch file it came from, so the patch keeps its name, shows as loaded in the palette, and SAVE writes back to it. Windows · Linux
14October 19, 2026ROOM fix: its stereo image was buried. The reverb tail came out about 18 dB too loud in the bass (and 8 dB in the mids), always leaned toward source 1's side, and was often out of phase between the two microphones. The tail is now at its proper level, equally loud in both microphones and decorrelated, and the default microphones stand closer (1.4 m) for a clearer image. Windows · Linux
13October 19, 2026The patch list is grouped by category (pianos and keys, organs, synths, guitars, bass, orchestra, saxophones, mallets, drums and more) and sorted by name within each group. Your own patches come first, under MY PATCHES. Windows · Linux
12October 19, 2026New LOGIC module: AND, OR, NAND, NOR, XOR, XNOR and NOT gates for 0 V / 1 V gates, clocks and LFOs, with a light on every jack. Windows · Linux
11October 19, 2026Two 70s prog-rock keyboard patches: PROG HAMMOND (a C3 driven hard into a fast Leslie) and MODULAR LEAD (fat detuned sawtooths, a steep swept low-pass, portamento). Windows · Linux
10October 19, 2026PIPE ORGAN: the swell box now moves smoothly, and the organ patches' expression pedal has its full range (about 11 dB). Before, their compressor flattened it. Windows · Linux
9October 19, 2026New PIPE ORGAN module: a large church organ with real stop tabs (principal chorus, mixture, flutes, celeste, trumpet and bombarde, 32-foot pedal) and seven organ patches, from a single principal to a huge full organ in a cathedral. New harpsichord patches. Windows · Linux
8October 19, 2026Cleaner, more articulate playing: bowed strings are damped when a note ends (no more open-string ringing), timpani are muffled when the key comes up (hold to let them ring), and the reed, brass and string models tongue / re-bow each separate note. Windows · Linux
7October 19, 2026Fix: in the orchestra's section patches (and the split / layer patches), every player after the first kept playing after the key was released. Sections now stop as they should. Windows · Linux
6October 19, 2026More realistic instruments: new physical models BOWED STRING, REED and BRASS, and a resonant BODY (violin, viola, cello, bass, guitar). The orchestra's strings, reeds and brass are rebuilt on them, and every player's intonation and timing now varies a little, as real players' do. Oscillators are band-limited: clean high notes. Windows · Linux
5October 19, 2026New ATTENUATOR module. A new ROOM starts as a treated music room (about 0.9 s of reverb instead of 2 s), so sounds keep a clear left-right position. Windows · Linux
4October 19, 2026Fix: in the plugin, a newly placed ROOM came up with every setting at its minimum and its microphones missing. It now starts with its proper room, materials and microphones. Windows · Linux
3October 19, 2026STEREO DELAY: stereo, ping-pong and LCR delays with DAW tempo sync, plus three example patches. SAVE and SAVE AS confirm when they are done. ROOM: the microphones are clearly marked, and a CONSTANT or an LFO now moves a sound whether or not notes are playing. Windows · Linux
2October 18, 2026Percussion: rock, Latin and African kits, talking drum, steel drum, balafon and kalimba. Every knob now has a scale in its own units, and the smallest panel text is larger and easier to read. Windows · Linux
1October 17, 2026First beta release. Windows · Linux
