G.ROUND

Features
Read full description

G.ROUND is a generative performance instrument built for musicians who want to create grooves, chord progressions, basslines, and evolving synth textures from one expressive interface. At the center of G.ROUND are two harmonic wheels: choose a chord, shape its color, change its mode, and instantly turn musical ideas into playable progressions. Every engine follows the other: drums, bass, synth, arpeggiator, recorder, and MIDI output stay locked together while you perform. Build a beat with the drum sequencer, design each drum voice with layered synthesis and modulation, generate basslines that follow your harmony, then shape a four-voice synth with oscillator, filter, envelopes, glide, LFO, delay, reverb, and advanced voicing controls. G.ROUND is not just a sequencer. It is an instrument that reacts to harmony. Record a chord performance, edit it as musical information, then keep changing the sound around it. Swap drum patterns, reshape the bass, alter the synth, enable the arpeggiator, change presets, or send MIDI to external gear without losing the progression that started the idea. Features: • Dual-wheel harmonic performance interface • Chromatic and diatonic chord control • Chord extensions, harmonic colors, and “Nerd Mode” options • Four-voice polyphonic synth engine • Arpeggiator with multiple rates, swing, gate, octave range, chord patterns, and variation • Monophonic bass synth with root, pattern, walking, melodic, acid, riff, and blues-style behaviors • Drum sequencer with kick, snare, and hi-hat lanes • Two-layer drum voice design with oscillator/noise, envelopes, filter, tone, and level controls • Per-drum modulation synced to tempo or free-running in Hz • Harmonic performance recorder with bar-synced recording and playback • Detailed MIDI track editor for recorded chord progressions • Up to 99 complete session presets • Global mixer with synth, bass, drums, and master volume control • Delay and reverb for synth textures • Voice-leading, strumming, modulation, and pitch-bend performance controls • MIDI output via cable, Bluetooth MIDI, IDAM, and CoreMIDI destinations • Multiple visual themes and adjustable internal sample rate Whether you are sketching a new track, exploring harmony, designing electronic grooves, or controlling external instruments, G.ROUND gives you a fast, tactile way to turn one gesture into a complete musical system. Start with a chord. Let the machine move. Shape everything.

Pythagorean Tuner is a precision tuner for violinists, cellists, violists, bassists, and singers who play in true Pythagorean intonation, built on pure 3:2 perfect fifths. Unlike equal-tempered tuners, it places every sharp and flat at its true, distinct pitch, so a flat sits lower than its enharmonic sharp, just as string players hear it.
