New version 1.4.2 β†’ 1.5.1

New SID GoatTracker .sid bank loading (PSID/RSID) β€” extracts instruments and macro tables from files packed by GoatTracker 2's exporter, with automatic detection of per-export feature flags (nopulse, nofilter, noinstrvib, fixedparams). Fixed SID program combo showing only the index (e.g. "001") with no instrument name after bank load β€” the patch-name update path was clearing the authoritative name from the bank file.

About

Legendary synths, samplers and keyboards reborn through cycle-accurate emulation. Now on iPhone and iPad with native AUV3 support. Retromulator is a multi-core retro hardware emulation app and AUv3 plug-in that brings legendary synthesizer, sampler, and keyboard cores back to life through authentic low-level emulation. Each core runs its actual firmware, physical model, or sample data β€” delivering the unmistakable character of the hardware that defined electronic music from the early 80s through the 2000s. EMULATED CORES Virtual Analog Synths (Motorola DSP 56300 recreation, interpreter mode) β€” built on the open-source Gearmulator by the dsp56300 team: DISCLAIMER: Apple's iOS App Store does not allow Just-In-Time (JIT) code generation in third-party apps. As a result, the DSP 56300 cores run in pure interpreter mode, which is significantly slower than the desktop JIT version. Expect higher CPU usage, reduced polyphony, and limited multitimbral capability compared to the desktop edition. A modern device (A14 / M1 or newer) is recommended for the DSP-based cores. Even on an M1 / A16-class chip, a high audio buffer size (high-latency setting) is required and polyphony remains very limited β€” these cores are not intended for low-latency live performance on iOS. β€’ Access Virus A, B and C β€’ Access Virus TI / TI2 / Snow β€’ Clavia Nord Lead 2X β€’ Roland JP-8000 β€’ Waldorf microQ β€’ Waldorf Microwave XT FM Synthesis: β€’ Yamaha DX7 β€” original chip set emulation, based on VDX7 by Charles Chiaccona β€’ Yamaha OPL3 β€” Nuked OPL3 cycle-accurate FM by Nuke.YKT Chiptune: β€’ Commodore 64 SID 6581/8580 β€” based on reSID. 3-voice polyphony, 8580 chip model with high-quality RESAMPLE, GoatTracker .sng / .ins bank loading (GTS3/4/5, GTI3/4/5), full macro playback engine (wavetable, pulsetable, filtertable, speedtable) and live MIDI control of cutoff (CC 74), resonance (CC 71), pulse width (CC 75), vibrato (CC 1) and pitch bend.
