Do you remember the single most iconic phaser you've ever heard? For the first time, there's a good chance of finding that exact sound captured in a plugin. FEATURES: • Faithful reproduction of a legendary 4-stage phaser pedal from the late 70's - early 80's • Complex effects can be built using composite LFO's, parallel phaser structures, as well as an independent modulation system for the sweep range • Barberpole or "Shepard" phaser included: infinitely rising / falling modulation that can optionally be combined with sweep range modulation • Strong, rhythmic / syncopated patterns can be created by configuring different LFO frequency ratios within the various modulation sources • Mid-Side modes allow adding special phasing effects to stereo sounds • Exact visualization of the notch filters' real-time frequency response, with different stereo options • Exceptional multirate performance: results are less sampling rate-dependent than what's currently available with most digital phasers (even from major manufacturers) • Designed to be an anthology app extensible with additional hardware-based or synthetic analog models in future MIDI NOTE EVENT RECEPTION: RealPhase can accept MIDI note messages, syncing an envelope-based modulation source to note on and off events. This makes it easy to use RealPhase as a powerful analog modeling OTA-based resonant notch filter with any synth or sampler. PLEASE NOTE: • An Audio Unit v3 compatible host app is required to use this plugin • Supported sampling rates: 44.1, 48, 96 kHz
Drum
This app recreates the distinctive sound of early 1980s electronic drum modules combined with sampled real cymbal sounds. It offers a virtual analog engine for drum synthesis and a separate engine for realistic cymbal playback, providing a unique sonic palette for music production.
- Virtual analog engine for 80s drum sounds
- Sampled real cymbal sounds
- Dual sound engines for drums and cymbals
- Multiple output options
- Built-in effects (limiter, delay, reverb)
- Unlimited program storage

Please note: 1) This App comes with an AUv3 plugin extension. 2) To play the cymbal samples, a separate download (free, in-app) of ~180 MB is required. The App also works without the cymbal samples. INSTRUMENT BACKGROUND We all know and use electronic drums today, but at the beginning of the 80's the first electronic drums were a real novelty that revolutionized not only the sound of music of those years, but also the workflow in the recording studio. Many producers preferred to record the sound of electronic drums rather than acoustic drums because it saved time and money, avoiding having to mount microphones, find the right positions, spend hours equalizing and correcting the recorded material. With an electronic drum set it was quicker: it was enough to connect the cables and maybe find the right sound for the song, which was a perfect scenario especially for many low-cost productions, for example those of pop music. The first electronic drums were completely analog, they generated the sounds of the drums using only a few elements such as an oscillator and a white noise generator, plus a couple of envelopes and a filter. The sound wasn't exactly realistic but it was peculiar, and perfect for creating certain sounds never heard before. The downside was that electronic drums could only generate the sound of drums but not cymbals. For this reason, the sound of real cymbals was recorded alongside the sound of electronic drums. This kind of setup was also used live quite often. It was common to see a drummer on stage playing the typical hexagonal pads but combined with a set of real cymbals. GSi Drum-80 reproduces that exact scenario. It contains two separate sound engines that can play at the same time. One engine recreates the sounds of the famous electronic drum module known as the Simmons SDS-V (very similar to the later SDS-8 model); at the same time, the exclusive GSi WLF Engine plays a multi-sample of real cymbals recorded exclusively for Drum-80. Main features - Virtual Analog Engine based on the famous SDS-V drum module - Optional VCO phase reset - Supports multiple outputs (one stereo mix, six individual drum synth channels, one stereo channel for Cymbals) - Sampled Cymbal sounds (Hi-Hat, Ride, 4 Crashes, 3 Splashes) provided by the exclusive GSi WLF Engine - Full Polyphony - Separate section with adjustments for Cymbal sounds (tuning, leveling and EQ) - Stereo 1176-Style Limiter - Stereo Delay effect - Stereo Reverb effect - Built-in programmer with unlimited Programs - Embedded user's manual - Available as Stand-alone application and audio plugin (AUv3 for iPad) - Very low CPU and RAM usage Visit home page for audio and video demos.
