About

JAF Model One

This stereo audio effect plugin offers a virtual analog transistor ladder filter with self-oscillation capabilities. It features audio-rate modulation, onboard saturation for analog drive, and MIDI connectivity for real-time parameter control. Switchable between low-pass and high-pass modes, it can enhance individual tracks or entire mixes.

Highlights
  • Virtual analog transistor ladder filter
  • Self-oscillation capability
  • 24dB cutoff slope
  • Low-pass and high-pass modes
  • Stereo audio processing
  • Audio-rate modulation oscillator
  • Inbuilt saturation unit
  • MIDI connectivity for parameter automation

The MODEL ONE is a selected, fine-tuned general purpose (transistor ladder model) analog modelled filter with the ability of self oscillation. The cutoff slope is approximately 24dB. It can be switched to low pass or high pass processing mode. The Model One, like all our filter models, is a true stereo processing audio effect, which includes a special audio-rate (high frequency) modulation oscillator, that can modulate the main parameters of the filter to its extremes. The modulation oscillator is not related to the inbuilt unison oscillators, which is a complete separate, different unit. All our models have also an inbuilt additional saturation unit for the extra bit of analog drive. This saturation unit and the oscillator section can be used without the filter module, because the filter unit can be switched to pass the incoming audio signals thru. The available vintage warmer tube/tape saturation type for instance is an excellent choice for breathing life into any obvious digital audio material. It can be applied to entire mixes as to individual tracks and voices. The hosting app for the Model One has special MIDI connectivity, thus parameters can be automated with realtime MIDI Controllers (See MIDI implementation chart).  The MIDI features on the audio unit depends on the fact, whether the host application will send MIDI messages to the plugin in any way with the audio processing block or not. The audio unit can be loaded into all supporting audio unit hosts. If successfully loaded into a host, all parameter automation and preset handling will be handled by these host applications.

Orbeat is a drum machine in the round. Instead of a grid, your rhythm lives on a glowing mandala — concentric lanes of light that orbit a single play button. Tap the rings, watch the playhead sweep, and feel the groove move. Built to be played, not programmed. Open it and you're already making beats. A CIRCULAR SEQUENCER — UP TO TWELVE LANES Six lanes wrap the screen as rings, and the circle can grow to twelve: the mandala opens a second page of rings in its own electric color set, so every lane keeps its full size. Tap to place hits, lock a lane you love, mute and solo as you build the groove layer by layer. The whole pattern turns as it plays. FOUR DRUM KITS Classic, Acoustic, Glitch, and 8-bit — one tap reskins every voice while your pattern stays put. From clean and punchy to broken and chiptune. BRING YOUR OWN SOUNDS Build a custom kit and drop your own audio into any lane — WAV, AIFF or mp3, up to ten seconds, played at its original pitch and in stereo. Imported samples run clean to the output, while the lanes you leave alone keep their synth voice, so a hi-hat you recorded yourself sits right next to Orbeat's own drums. Your first custom kit is free. GENERATORS THAT SURPRISE YOU Roll the dice for an instant pattern, or use Euclidean rhythms to spread hits evenly around a ring. Like what you hear? Tap the ring to write it in and edit by hand. MAKE IT BREATHE, MAKE IT DRIFT Add swing to push the feel off the grid, draw velocity per step for accents that live, and pan each lane across the stereo field. With Probability, hits fire by chance; with polymeter, each lane gets its own length so the phases drift in and out of sync. TAKE IT ANYWHERE Bounce any loop to a stereo WAV — named with the beat, its length and its tempo, so it still makes sense in your DAW next month — or run Orbeat as an AUv3 instrument with MIDI in & out — sequence other instruments, or play Orbeat's lanes from your host's piano roll inside GarageBand, AUM, Logic, and other AUv3 hosts. Standalone, play the pads live from any MIDI controller and sync the whole groove to external MIDI clock. PLAY IN SYNC WITH THE ROOM Ableton Link keeps Orbeat in time with every Link-enabled app and device on your network — Ableton Live, AUM, Loopy, a friend's iPad across the table. Tempo follows the session, start and stop are shared, and everyone stays in phase. No cables, no setup. PLAY FREE. UNLOCK ONCE. The full instrument is free forever — every kit, the six-lane circle, Euclidean generators, swing, velocity, pan, your first custom kit with your own samples, MIDI in & out, and Ableton Link. Orbeat Pro is a single one-time purchase (no subscription, ever) that unlocks room to grow the circle to twelve lanes, plus Probability, polymeter, WAV export, unlimited saved beats, and extra custom kits. Made for iPhone and iPad. No account, no ads, no tracking — your beats never leave your device unless you share them. Tap the rings. Make it move.
