- 📦Retromulator updated to version 2.1.8Matrix-1000 and DX7 no longer need firmware: both run on clean-room controllers written from the behaviour of the hardware, and play without a ROM installed.
Matrix-1000: the six voices are processed together and use less CPU. LFO sync moved to the LFO 1 and LFO 2 boards: a Sync button next to the Wave menu, and while it is on, the Speed knob picks the tempo division. Turning sync off restores the patch's own LFO speed. User .syx banks load as before, and the patch memory and master settings are saved with the project. Projects that played a patch from the internal memory find it by name in the Matrix banks.
DX7: about 45% less CPU, and the first note after a preset change plays. Pitch bend range defaults to 2. Bend, mono, portamento and glissando settings are saved with the project, and the controller setup in the bank menu shows what the engine uses, including function SysEx received over MIDI.
Loading a project or preset on the core that is already running no longer restarts it (Matrix-1000, DX7, OPL3, Ayumi, OpenB3, CA-72, OpenWurli and Nordic).
Board controls show the saved values after loading a project or preset, and board edits are saved with the project.
Board controls and labels are drawn sharp at every size.
Nordic: MIDI CC Table in the bank menu. Programs above 40 in the Sound Card banks can be selected from the host. Fixed a black Nordic panel when the window was opened again.
Fixed possible hangs while a host records automation of Nordic parameters.… more - ✏️Retromulator: needs a newer iOSiOS 15.0 → iOS 16.0

- 📦Retromulator updated to version 2.1.5Nordic: a new virtual analog core with its own panel. It imports Nord Lead SysEx dumps and Clavia's factory banks (.syx, .mid and .zip) and comes with the Internal factory bank and the Sound Card 1-4 banks. MIDI program changes select programs from the loaded bank. In a host, Nordic loads as its own AUv3.
The effect chain hosts Audio Unit effects: Apple's effects and installed AUv3 effects in the app, Apple's effects in the AUv3. Add Effect lists them by category. An effect that crashes while loading is set aside and can be allowed again under Crashed Effects. Apple's effects are edited on the board.
The FX button is shown next to the bank menu for every core, so an effect chain can be set up on a running core.
Nord Lead 2X: the output is 12 dB lower, at the level of the other cores.
Nord Lead 2X board: names for every switch, plus LFO sync, unison detune and bend range.
Board pages that fit the screen height share a tab, and tab names are no longer cut off.
Panic in the bank menu of every core: sustain off, all sound off and note-off for every note on all 16 channels.
Import App Data URL Backup accepts a link copied as a URL or as text, and reports an invalid link before downloading.
Standalone app with the keyboard: the rack, the panel and the keyboard stack up from the bottom in any orientation.
Unassigned host parameters are named Slot 1 to Slot 128.
Fixed DX7 crackles.
Fixed CA-72 POLY dropping every other note on iPhone.
Fixed a crash when loading the Virus, microQ and Nord Lead 2X cores, and a crash when removing an effect.

- 📦Retromulator updated to version 2.0Boards: a control panel under the rack for 15 cores, with knobs, faders, switches and value lists on pages laid out like the hardware sections. Boards follow patch loads, incoming MIDI and host automation.
Boards are available for the Virus A, B and C, Virus TI, Nord Lead 2X, JP-8000, microQ, Microwave XT, DX7, Matrix-1000, OPL3, SID, Ayumi, OpenB3, Wurlitzer, Akai S1000 and the SC series.
The board and the on-screen keyboard can be shown or hidden from the bank menu. On iPhone the board takes the keyboard's place.
Hold a board control to link it to one of the 128 host parameters. Links are saved per core and in the project.
NRPN input, enabled per core, sets the core's own parameters.
The core can be selected over MIDI with SysEx F0 7D 52 4D 01 cc F7 or NRPN 127/0.
MIDI out for board edits and for the core's own output, both optional. The AUv3 sends them to the host. The standalone app sends them to a MIDI output device and channel chosen in the None core menu, so a board can edit external hardware.
Editor Only, in the bank menu of each core with a board: the board runs without the sound engine, and without firmware, to edit the original synth over MIDI out. The Firmware Not Found dialog also offers Use as Editor.
The core menu is grouped into Virtual Analog, Analog, Wavetable, FM, Chip, Keyboard, and Sampler & GM.
Fixed extra latency on the SID core when it was selected from the core menu.… more - 📦Retromulator updated to version 1.11New CA-72 core: Minimoog Model D circuit model by Idle Foundry. Three oscillators, mixer with noise and external input, filter and loudness contours, plus a voice section with Double, Detune, Width and Entropy, output Drive and Level, and LO, HI and ULTRA quality modes.
CA-72: front panel shown below the rack with its own pitch and mod wheels. It can be hidden from the bank menu.
CA-72: 46 factory presets and a User bank. Presets are .fxp files, banks import and export as .fxb, and MIDI Program Change selects them.
Standalone: MIDI In channel (Omni or 1 to 16), MIDI In device selection and Bluetooth MIDI pairing in the Options menu of the None core.
Show MIDI Keyboard option to hide the on-screen keyboard and wheels.
Fixed OpenB3 Rotary Speed not following the mod wheel and sustain pedal.… more - 📈Retromulator entered the top 10 on iPad · Top Paid All AppsAR
- 📦Retromulator updated to version 1.9.1DX7：モジュレーションホイール、ブレスコントロール、フットコントロール、アフタータッチの初期設定を、レンジ 99、Pitch・Amplitude・EG Bias すべてオンに変更しました。各パッチで設定したモジュレーションがそのまま効きます。
DX7：バンクメニューにコントローラーごとの設定項目を追加しました。レンジの変更と、Pitch、Amplitude、EG Bias のオン／オフができます。設定はセッションに保存されます。
Matrix-1000：オシレーターが、実機と同じくエミュレートした 8254 タイマーのエッジでリセットされるようになりました。DCO 1 と DCO 2 の位相関係がファームウェアの動作どおりになります。
Matrix-1000：DCO シンクを回路図どおりの回路に変更しました。Soft、Medium、Hard は実機と同じ動作になり、以前のバージョンとは音が変わります。
Matrix-1000：コントロール電圧に実機の DAC レンジとサンプル＆ホールド回路を反映しました。エンベロープ、フィルタースイープ、パルス幅変調の段差が滑らかになります。
Matrix-1000：パルス幅 31 が正確な矩形波になりました。
Matrix-1000：VCA のカーブを CEM3396 のデータシートに合わせました。フィルター FM はパルスを含まない DCO 1 の波形から取り、レゾナンスを上げるとフィルターに第 2 倍音が加わります。
Matrix-1000：出力段をリニアにし、和音が圧縮されないようにしました。
Matrix-1000：このアップデート後、最初に読み込むときにコアが再キャリブレーションを行います。
Matrix-1000 の DCO 2 が、ノートが変わったあと新しいピッチに落ち着くまで実機の 2 倍の時間がかかっていた問題を修正しました。… more - 📦Retromulator: now updating weekly4 updates in 30 days, after a quiet two months

- 📦Retromulator updated to version 1.9New core: Oberheim Matrix-1000. The original firmware runs on an emulated Motorola 6809 board that drives six CEM3396 voice models. Banks 2 to 9 load from the patch EPROM, and each of the 96 patch parameters has a MIDI CC.
Matrix-1000 LFO 1 and LFO 2 can sync to the host tempo or incoming MIDI clock, set from the bank menu and stored with the session.
Matrix-1000: MIDI Bank Select (CC 0 or CC 3) picks the bank file and Program Change picks the patch, the same as choosing them in the menus.
Wurlitzer 200A: the OpenWurli model is updated to version 0.9.0, with a new pickup model, reed swing and air damping from per-note hammer tables, a new preamp solver, a tremolo with the real LED response, and the power amp and volume control networks from the schematic.
Wurlitzer 200A: parameter changes are smoothed. The Pickup switch is now called MLP Corrections and is off by default.
New MIDI CC Table at the end of every core's bank menu, listing each mapped controller.
Tracker core: new Loop In and Loop Out points, set from the playing order with the F0 and G0 keys or with the host parameters and CC 20 and CC 21.
Tracker core: new Wait for Pattern End option, on by default, so position keys jump when the playing pattern ends instead of cutting it off.
The firmware picker accepts several files at once, for cores that need two ROM dumps.
Fixed the app hanging when switching from a DSP core such as the Virus to None.… more - 📦Retromulator updated to version 1.7.3Host parameters now show the values of the loaded patch on the JE-8086, Virus, MicroQ, XT, N2X and DX7 cores.
New host parameters: Virus sub oscillator, ring modulator, unison, keyfollow and LFO symmetry; MicroQ glide rate, Osc 2 FM and more envelope stages; XT glide time, FM amount, Osc 2 octave and modifier amounts; N2X filter envelope attack; Tracker volume.
Parameters that had no effect on a core are now hidden.
Fixed JE-8086 filter cutoff and other sound parameters not responding to host automation.
Fixed 88emu cutoff, resonance, envelope and vibrato automation on the SC-55mkII, SC-88, 88VL and 88Pro, and the delay level, feedback and send to reverb parameters changing the wrong setting.
Fixed the Sustain and Portamento parameters never switching on.
Fixed host automation going out on the wrong MIDI channel after editing an 88emu part other than part 1.
Fixed DX7 Expression having no effect at full volume, and Wurli Expression replacing the volume setting.
Fixed the Wurli Pickup switch not turning on.
Fixed Akai S1000 volume, pan, modulation and expression not applying to notes played after the change.
Fixed the Ayumi envelope shape parameters reaching only part of their range.
Fixed the standalone app losing the loaded synth and patch when iOS closed it in the background.
88emu: system SysEx in MIDI files, such as mode and part input settings, now reaches the SC-88 firmware, and truncated MIDI files no longer read past the end of a track.… more - 🆕Retromulator first spotted by AppInsider#65 in Top Paid · Music · Italy

About Retromulator
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 original firmware, a clean-room controller written from the behaviour of the hardware, a physical model or sample data — delivering the unmistakable character of the hardware that defined electronic music from the early 80s through the 2000s.
