Loop'Dup is an audio clip player, sample arranger and loop sampler. Bring your loops into one app to sample jam, experiment, create live sets and absolutely have lots of fun! Loop'Dup! - Infinite beats, endless inspiration. This app was made entirely with solar power. Each track can launch a clip anytime, in-time with the master tempo. Every project contains 8 sets of 8 clips per track. One track can have up to 64 audio loops available to play at anytime. You could arrange sets as a songs and each row is a song part. Or each set arranged as a genre of clips (Beats, Bass, Synth etc) Perform a whole live -set. Arrange clips as rows or launch a clip from any set. All tracks have separate send effects levels of delay, reverb, dual filter. Track FX can be muted on or off as well as track volume. A special TempFX state can be used to freely play with FX sends then revert back to previous state instantly. Launch rows of clips simultaneously for arranging parts or scenes. Sample into a clip at anytime using bult in microphone or external USB audio device (class compliant). While sequencer is playing it samples a fixed length (chosen in settings) and starts at the nearest quantised bar (chosen in options). Choose to manually start sampling (waits for slow signal) when sequencer is not running, stop sampling manually or wait for the chosen fixed length. It can also auto-play like a looper Resample what is playing including any FX into an empty clip to bounce multiple tracks into one clip. Load audio files into a clip from the "Samples" folder located in this Documents folder. You can also use AudioCopy general pasteboard to conveniently copy audio between apps. AudioPaste directly to a clip or copy the audio from a clip and AudioPaste into another supporting app. Includes a demo project containing 3 sets of audio clips Also included are some audio loops captured from 2XB303, 7XDXFM, 7XWAVE, 6X806 and PunkGen with some other drum loops to help get you started jamming. The included audio loops are electro synth based. Manually set an audio clip settings: Sample duration from 8 to 128 steps (sixteenths), Reverse, Stutter effect, Auto pitch to adjust pitch to fit length of clip or manually transpose for one-hit samples, Gain override, Loops count (how many times a loops a clip will repeat), Next-Clip ( auto launching a different clip loops have finished). Send MIDI out clock to external MIDI synths, drum machines or grooveboxes so they play in time while also sampling them. You can, for example sync to the Roland MC101/MC707 via USB and send MIDI clock while sampling the MC101/MC707 own audio back into loopD'up Up to 10 projects can be loaded at once and you can export consolidated projects or import backed up projects into a project slot. 3 Different metronome modes to help you sample in time. Latency setting to compensate for microphone delays. Ableton Link to sync with other apps. IAA to route audio into Audiobus, AUM or other supporting apps to process live audio or sample. Loop it. Layer it. Love It! Loop'Dup - Your pocket sized Studio! Specs: Time synced Delay FX speed . Auto play after sampling option. Launch quantize settings from 16 steps to 128 steps. Clip length options from 8,16,32,64,128. 8 Sets A - H per project. 8 Clips per each set. 64 Audio clips per track can be loaded. Ableton Link sync. USB audio device support up 44.1k or 48k only (class compliant). USB MIDI device support (class compliant). MIDI out sync. Audio latency adjust up to 100ms IAA Audio output. Memory efficient disk streaming of audio. Auto normalise option (default) 10 projects loaded at any time. Monitor audio in option. To get audio files from outside your device into the app you can transfer audio using airplay, iCloud or usb and copy into the samples folder located in this app's documents folder. You can access this folder using Apple's Files application. Any problems be sure to contact via the email link in information

• AUv3 plugin to modulate and sequence MIDI instruments and modular hardware • Outputs MIDI and analog CV simultaneously for integrated hybrid setups • Fully functional in software-only environments with full MIDI support • Converts LFOs, MIDI notes, pitch, and control changes into control voltages • Includes two LFO generators with random spline, cross-modulation and syncing • Integrated envelope follower to track audio input or sidechain signal • Six FLO(W) processors for combining and shaping signals with math and logic • Each FLO supports 18 inputs with individual polarity, divider and multiplier • Multi-out support, built-in waveform viewer, Audio FX, and MIDI FX • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Polyflo is an AUv3 plugin for modulating and sequencing MIDI instruments and modular gear via control voltage. It outputs MIDI and analog CV simultaneously, making it well-suited for hybrid setups that combine digital and analog equipment. The plugin includes two LFO generators offering 10 waveforms, including classic shapes and random spline, with support for cross-modulation and syncing. It also features an envelope follower that tracks audio FX input or an external sidechain. The generated signals, together with the host clock and MIDI input, are fed into six independent FLO(W) processors. These processors combine, shape, and route inputs using math operations, conditional logic, and comparators. Each FLO includes individual polarity, division, and multiplication controls, providing deep and flexible modulation that balances chaotic creativity with precise timing. Each FLO processor output is connected to its own output bus, enabling easy integration with hardware via DC-coupled audio interfaces like the Expert Sleepers ES-9. For simpler setups, FLO outputs can be routed to the stereo output. FAC Polyflo can also convert MIDI notes, pitch, and control changes into control voltages, making it a powerful MIDI-to-CV solution. If you prefer to work exclusively with software, the plugin runs smoothly in software-only environments with full MIDI support, making it equally suited for purely digital workflows. FAC Polyflo works as both an Audio Unit FX and MIDI FX, featuring a clean, touch-optimized interface with precise control and waveform visualization. It’s available as an AUv3 for iOS (iPad/iPhone), macOS, and Vision Pro, and requires a compatible AUv3 host app to run. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Polyflo.html
