VAPolyLead features 3 channel analog style step sequencer and a VCF modeled on sallen-key filter of iconic monophonic synthesizer in 1970’s. This polyphonic synthesizer consists of three oscillators, resonant low pass filter resonant high pass filter, amplifier, ADSR envelope and five LFOs. VAPolyLead operates as a stand alone or as an AudioUnit Extension (AUv3) for iPhone, iPad and Mac. Stand Alone supports Ableton Link, MIDI and audio file export. Built-in Effects include delay, chorus, flanger, reverb, eq and compressor. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac. Main Features - Polyphonic Synthesizer. - Lowpass filter modeled on -12dB per oct sallen-key filter. - 3 channel analog style step sequencer. - Maximum 8 voice polyphony. it depends on performance of the device it is running. - Built-in effects and piano roll sequencer. - Audio Export. Linear PCM format (AIFF, WAV and CAF) and compressed format (AAC) - Support Audio Unit Extension (AUv3). - Support MIDI 2.0. Support Foot Pedal. - Support Ableton Link, Bluetooth MIDI, MIDI In / Out. - Works on iPhone, iPad and Mac. Support iCloud Drive to share project files between the platforms. - Factory Preset: 128, Effects: 40 Improvements - Support MIDI Foot Pedal (CC#11, CC#64) - MIDI CC Settings are saved. It will be recovered when the app launched in the next time. - UI Color can be selected from black, navy, gray or steel. System Requirements - iOS 17.0 or later - Devices with Apple Silicon are recommended. A13 Fusion or above is highly recommended. - AudioUnit Extension (AUv3) requires host application which support AudioUnit Extension. - AudioUnit Extension is supported by Apple Logic and Apple Garage Band on iOS and macOS. For any other DAW, it depends on the application and some of them don’t support AudioUnit Extension. - Sound may be distorted if CPU of the device doesn't have enough power.

TwinPath enables parallel effects processing using your existing Audio Units, without configuring busses or complex routings. It hides the details of managing multiple signal paths, and offers a compact, quickly accessible control interface. The result is a consistent setup you can easily recreate in any DAW, regardless of how each host handles audio routing. Among its possible applications, TwinPath pairs especially well with delay effects for dynamic performances. Shifting focus from deep editing to switching between (or blending) entire modules opens up a new perspective and new features – especially when feedback delays are involved. And of course, both approaches can be applied at the same time. Once inserted into a track’s effects chain, TwinPath handles splitting and merging audio streams and provides several convenience features. It offers two main classes of operation: CROSS-FADE • Blend between two effects chains using a single control • Switchable pre/post operation: pre mode preserves effect tails and lets feedback effects "breathe", while post mode offers instant, direct control DUAL MONO • Run different effects chains for Left/Right, Mid/Side, or a continuous blend between them • Channel mapping and FX bias are smooth, performance-friendly controls • Quick and efficient workflow replacement that overcomes functional limits of stock dual mono modes, such as restrictions on independent preset loading PLEASE NOTE: • An AUv3-compatible host is required to use this app
