Lil' Doc is a compressor effect based on the muscular, vinyl simulator in an early 00s workhorse sampler. It’s a powerful effect that’s found a cult following among lo-fi heads, and rightly so! We first implemented this compression algorithm for our paid plug-in Doctor Vibe, and the sound was so unique, we thought it would be a great first entry in our free plug-in series. Enjoy! Features: - Completely free, no unlock required! - Four controls: - Detroit-style mix slammer - Warm vinyl noise and crackle - Drive to clip the converters! - Four sample grades to choose - Output gain - One-click loudness matching - Light or dark color scheme. Lil' Doc is an AUv3 effect plug-in. For best experience, load the plug-in on an effects slot in a compatible host. You can also preview the effect in the standalone with our new mini-player.

GCS Model 8 is a free, pocket-sized 8-track tape DAW for iPhone. It has a full blown physics engine which runs in the background and models classic reel-to-reel machines and various formats ranging from LoFi cassette to HiFi 1" tape. The engine is the exact same as the one used in the professional desktop recording version, but still runs very nicely on iPhone. GCS Model 8 for iPhone is completely free, with no in-app purchases, subscriptions, or ads. I really want people to have the engine as a fun tool for mobile settings without any sort of catch. Features: • 8-track recording with a real tape transport (play, record, rewind, fast-forward, punch, scrub) • Analog tape physics: adjustable wow, flutter, stickiness, head gap, hiss, and age • Built-in effects and tape techniques: reverse, SOS, punch, click track, loop • Built-in instruments: A-1 Mono Synth, A-10 Poly Synth, Glissandio (Ondes Martenot style slide synth), Stage Keyboard • Voxtone Drum Machine: synthesized analog drums with a dedicated step-sequencer (MATRIX) and live-trigger (PADS) view, plus two sample-based kits (808, Acetone) • 8-pad MPC-style Pad Sampler: load your own samples or mic them in directly, with pitch, trim, and gate controls • Reels: save, load, and share your sessions • Bluetooth MIDI keyboard support • Importing recordings to hit them to tape • Sound of Sound looping (Fripp style) • Formats: cassette, 1/4", 1/2" and 1" - along with various presets •Most of the features found on the desktop version Reels you create on iPhone move over to GCS Model 8 for iPad and GCS Model 8 for Mac/Windows, which add more tracks, more effects, and full export/mixdown for when you're ready to take a session further.
