Bug fixes and control improvements. FIXED - Moving the ACID filter CUTOFF made the tone drop and then open up again when you let go (PATTERN modes) - The app could quit unexpectedly when a slider was moved continuously during playback - When one LFO modulated another LFO's DEPTH, the handle was drawn off the centre of its modulation range - Trying to drag a slider could switch the panel to a different page IMPROVED - CUTOFF, XY PAD and LFO now follow your finger immediately - The INIT preset's ARP B level is now 75%, matching ARP A

ARPJAM Studio now runs on the Mac (universal purchase — if you own it on iPad/iPhone, the Mac version is included). ■ Mac - Standalone app - AUv3 plug-in (instrument and effect) in Logic Pro, Ableton Live, GarageBand and more - Ableton Link ■ New sounds - New "EP" waveform — a synthesized electric piano voice - New oscillator "Character" — PURE (the exact waveform, as before) or ANALOG (analog-synth imperfection: imperfect shapes, slow pitch drift, random start phase, gentle saturation) - Envelope and filter settings are now remembered separately for three groups — the four synth shapes, PIANO, and EP — so switching waveform recalls that group's own settings ■ New - TIE switch — consecutive slots tie into one legato line (non-consecutive notes play as before) - MIDI out on a virtual port ("ARPJAM Studio OUT") — sequence your other instruments from ARPJAM, even in DAWs that cannot read plug-in MIDI output such as Ableton Live (ARP A=ch1 / ARP B=ch2 / DRUMS=ch10) - New Target setting in the plug-in — choose whether the host's MIDI plays ARP A or ARP B - Vel Sens in MIDI INPUT — boosts incoming velocity so a light touch can match the sequencer's level - Vel Sens in the Oscillator section — sets how hard the sequencer strikes (hand playing is unaffected) ■ Improved and fixed - Big reduction of audible zipper/click noise while adjusting parameters during playback (raising DRIVE from zero, send levels, STEREO WIDTH, switching reverb types) - Sliders are easier to grab (edge drags, coexistence with vertical scrolling) - iPhone layout fully reworked - Overview screen refined (uniform card heights; taller content scrolls inside its card) - Fixed horizontal swipes failing right after a vertical scroll - Fresh installs and newly inserted plug-ins now boot with the current factory preset - Fixed the plug-in importer sometimes rejecting valid .arpjam files - Fixed the export name dialog escaping small plug-in windows

Thank you for using 2.0. This update fixes a few problems and evens out the levels. ■ The waveforms are now level-matched Switching between sine, triangle, saw, square and piano no longer changes how loud the instrument is — every shape was measured and matched. The piano in particular used to sit below the rest. ■ Clicks removed • Moving CUTOFF or KEY FOLLOW while notes are sounding • A small click at the head of every sine note ■ Piano In a DOUBLE, the first of the two strikes could be silent. It now behaves the way a real piano does, the second strike taking over from the first.

ARPJAM Studio has been rebuilt from the ground up. A new engine, written in native Swift — it behaves differently and it sounds different. ■ Play it from a MIDI keyboard Connect a keyboard and play directly. Damper pedal, pitch bend and the standard control changes (cutoff, resonance, ADSR, send amounts) are all supported. What you play lights the key pad and records straight into the looper. ■ AUv3 plug-in Use it inside AUM, Logic, GarageBand and other hosts, as an instrument or as an effect. Run several at once, or put ARPJAM's texture on another track. ■ A new piano Three velocity layers, so playing softly changes the tone and not only the volume. Recorded and played back in stereo, with the damper sound as a key is released and decay lengths chosen per register. Re-striking a key now behaves the way a real piano does. ■ Key Follow (new) A control that takes less away from the bass as you close the filter, so low notes keep their body however dark you go. ■ Texture DRIFT and FLUTTER tape movement now runs on the synth voices and on the live input alike. Every voice follows the concert-pitch setting (A=415–444 Hz). ■ Glitch / Granular Their reverb tail now matches HALL, and both have real stereo width. ■ Audio input Cleaner line and microphone capture, plus a HUM FILTER that removes mains hum. Everything is native Swift now: lighter, tighter timing, and easier on the CPU.

Fixed sustained playing on the PLAY PAD. Held notes now ring for as long as you hold them instead of cutting off early. Plus stability improvements.

ARPJAM Studio 1.1 — a major update ● RECORD: capture everything you hear as a WAV file and share it via AirDrop or Files ● INPUT: bring a USB-C audio interface or the mic into the app — monitored and recorded together with the engine. Noise gate, low-pass and delay/reverb sends included ● TIME SIGNATURES: 10 meters from 3/4 to 12/8, with drum grids and beat dots following along. 7/4 and 7/8 offer accent-grouping variants, plus an ACCENT VEL switch that emphasises the strong beats ● New mode "Random Motif": composes a one-bar phrase by itself, loops it, and evolves it bar by bar. Save phrases you love into Pattern 1/2 and fine-tune them by hand ● CONTOUR: gives random note picking melodic inertia — raise it and randomness turns into singable lines ● Smoother touch: horizontal scrolling no longer fights sliders and switches, and the parameter help popups have been redesigned for readability ● Many stability improvements and bug fixes The manual has been fully updated: twelvetone.jp/arpjam-studio/manual/index.en.html

Minor bug fixes and stability improvements.

• Preset export now works when the app runs on Mac (Apple Silicon). • Improved the startup tutorial — added the Arpeggio Type step and tidied the order. • Minor tweaks and stability improvements.

• Generative notes now appear as each oscillator's waveform icon. • The Fifth layer now sounds on the Piano voice too. • Avoid Mode is now available in Pattern mode — choose whether the added fifth stays in-scale or plays on every note. • Minor tweaks and stability improvements.
