LogSynth vs TONAUT

LogSynth is a polyphonic virtual-analog synthesizer built for people who care what's actually happening in the signal path, not just what the preset browser looks like. Every voice runs five anti-aliased oscillators (sine, triangle, saw, pulse with PWM, and a band-limited impulse train) plus a dedicated sub-oscillator and noise source, mixed per-voice with independent amp envelopes. Chunky oscillators, crisp effects and a zero-delay-feedback state-variable filter — switchable low/high/bandpass. The drive effect is powered by a physically modeled diode circuit, numerically integrated rather than a lookup-table approximation, so pushing it into saturation behaves the way an actual analog drive would. FEATURES - 8-voice polyphony, 5 oscillators + sub + noise per voice - Zero-delay-feedback state-variable filter with resonant feedback and diode drive saturation - 5 independent oscillator envelopes plus a dedicated filter envelope - 2 assignable LFOs and an 8-slot modulation matrix - Built-in chorus, delay, FDN reverb, and 4-mode distortion - 41 factory presets across Bass, Lead, Pluck, and Effects - One-tap patch randomizer with adjustable intensity - Real-time oscilloscope, on-screen keyboard, and CoreMIDI input - Runs standalone or as an AUv3 instrument inside AU hosts Whether you're sound designing from scratch or dropping it into a DAW as a plugin, Logsynth gives you the same engine everywhere — no watered-down mobile version, no feature gating between standalone and plugin modes.

Tonaut is a synthesizer, drum machine, sequencer and eight-track tape recorder in one instrument, made to be played rather than programmed. Pick a sound, tap out a pattern and record it to tape, all on one panel that feels more like hardware than an app. IPHONE DUO • Folded, one octave on the outer screen. Half folded, the screens above the keys. Open, the whole instrument. Folding never stops the music SOUNDS • Nine synth engines: virtual analog, six-operator FM, wavetable, pulse, modeled string, a seven-oscillator swarm, grains, a classic analog poly and a sampler • Every engine has a 3D screen that moves with your playing, or a classic view • Over 500 sounds, from warm pads to glassy bells and growling bass, including 147 sampled instruments • Edit every sound in depth, save your own, and star your favorites • Load DX7-style SysEx banks into the FM engine • Four effects on every sound from sixteen types, from tape echo and huge reverb to distortion, pump, phaser and lo-fi • A master effect, a master EQ and an EQ on every lane DRUMS • 43 kits on three drum engines: kits made from real recorded drums, synthesized kits where every pad is its own drum, and slice kits • Knock and Cinder kits drawn in 3D, moving with every hit • A groove player: hold any pad and the whole kit plays one of sixteen grooves • Make kits from your own recordings or from audio files, one per pad KEYS AND CHORDS • Pick a key and scale and its keys light up; LOCK keeps every note in key, per lane • CHORDS plays a whole chord from one key, and works with the arpeggiator and the sequencer • Chord pad: seven chords from your key and a stick that turns each into a 7th, 9th, sus, dim and more, with strum and bass, also from a MIDI keyboard SEQUENCER • Eight lanes, each with its own sound and sixteen patterns of up to 64 steps • Write step by step or record live, with chords, slides, ratchets and chance • STEP REC: each note or chord you play fills a step, with rest and tie, also from MIDI • Pattern Play: queue the next pattern and every lane moves on together • Copy, swap and transpose patterns, and reorder lanes • An arpeggiator on every synth lane PLAY IT LIVE • A Perform page with TONE and SPACE for every lane, which glide back when you stop • An X/Y pad that bends pitch and moves the sound under one finger • One-tap mutes, tap tempo, click and count-in TAPE • Eight tracks of 20 minutes each, or six tracks of 30 minutes, chosen per project • Record every lane to its own track, or several onto one • Loop, reverse, stutter, brake and catch the last 30 seconds you played • A tape mixer, and pinch to zoom from a few bars to the whole song SAMPLING • Sample with the microphone, a USB interface, or Tonaut itself • Link your sample folders once, tap a file to hear it, and load it onto a pad or into the sampler • Drag audio files in from other apps onto a drum pad or the sampler MIDI • Play Tonaut from USB or Bluetooth MIDI keyboards and controllers, on the selected lane or with each lane on its own channel • Send any lane to your own synths and drum machines, with clock and start/stop SHARE AND EXPORT • Share a loop from the tape as a vertical video or as audio, ready to post • Send a whole song, samples and all, as one file a friend opens in Tonaut • Export a stereo mix, separate stems as WAV files, or MIDI files of every lane • Optional iCloud sync between your iPhone and iPad One purchase covers iPhone, iPad and iPhone Duo, each with its own layout, in six looks: Light, Dark, TN-1, TN-1 Dark, TN-XY and TN-SIGNAL. No subscription, no account, and Tonaut collects no data. Your music stays yours. REQUIREMENTS • An iPhone with an edge-to-edge screen: iPhone XS, XR or newer, iOS 17 or later. Not the iPhone SE (its screen is too small) • iPad (6th generation), iPad mini (5th generation), iPad Air (3rd generation), iPad Pro (2017) or newer, iPadOS 17 or later Questions?
