The sound engine of the legendary Waldorf Streichfett hardware is now available for iPad including AUv3 format. The Streichfett takes you back to the days of the legendary String Machines. In the old days, there was no choice – to create a massive wall of sound, you simply needed a String Machine. It was the time when composing contemporary music had no resemblance to doing your annual tax return on a PC. It was the golden years of rock and pop, when even keyboard players simply plugged their instrument into the amp and started playing, instead of labouring over endless preset lists in search of the perfect sound. Now there is Streichfett – and the good old days are coming back. Experience what a real String Synthesizer sounds like. Experience how a homogeneous, extremely dense, floating web of sounds can be created from a raw, basic electronic sound in just a few simple steps. Streichfett combines the best of the previously extinct species of String Synthesizers of the 70s and early 80s. Its dual sound engine features a fully polyphonic String Section and an eight voice Solo Section, which is essential for recreating classic movie sounds from the 70s and 80s. The Ensemble Effect provides depth and movement to the String Section, while the Effects Section adds adjustable Phaser and Reverb effects. Additionally, the Animate Effect can be used to modulate the Strings Registration, allowing spectacular sound morphs. The Solo Section offers presets named Bass, E-Piano or Clavi, and just like with a typical String Machine, the sound has little to do with that name. Instead, these are shimmering and slightly percussive sounds that blend well with the String Section. Although the User Interface is simple and easy to comprehend, it controls a rather complex sound engine which is capable of delivering rich and creamy pads unlike any other instrument.

RS-1 turns your mobile device into a hardware-grade sequencer that feels like the real thing. Built for iPhone and iPad, it packs 6 tracks (8 on iPad), a tactile 16-step grid, and 8 joinable patterns you can chain into full arrangements. Drive any piece of hardware or software instrument with real-time MIDI 2.0 over Bluetooth, USB, or Wi-Fi, and lock everything to your rig with Ableton Link sync. Five unique tools let you edit, alter, and even scramble your patterns on the fly, building complex polyrhythms and melodies with just a few tweaks. The interface borrows its workflow straight from classic hardware sequencers: every control for every track sits right in front of you, so you stay locked into your musical ideas instead of menu diving. All of it slips right into your pocket. SEQUENCING The beat grid runs six horizontal tracks across sixteen vertical steps. Tap a cell to toggle its trigger gate. Each track has its own free-running playhead, so you can build polymeter by giving different tracks different effective lengths. Eight independent patterns share the same track routing - MIDI channels, mute/solo states, and output destinations carry across every pattern. Hold down the pattern buttons to chain them into a sequence, and use Copy/Paste to duplicate a pattern in a tap. FIVE CREATIVE TOOLS 1. Note Input Tool - Edit a track in focus view. Tap a track header to open five tabs, each assigning a per-step value: - Pitch: Set each step's pitch, quantised to a scale. Custom scales supported. - Velocity: Rescale overall velocity with a single slider. - Gate: Adjust note duration per step. - Ratchet: Set the number of repeats; a slider adjusts the repeat interval. - Chance: Probability-based step removal. 2. CC Tool - Edit a track's MIDI CC messages in focus view. Tap a track header to open five tabs: four CC slots plus a Program Change tab. Draw automation curves for filter sweeps and modulation, or send program changes manually for preset switching. 3. Combine Tool - Stitch adjacent steps into longer, legato notes. Drag across cells to select, then press Combine to join them. 4. Time Tool - Shape playback per track: Division (step length), Shift (rotate the pattern in time), Swing, and Loop length. 5. Order Tool - Choose from 19 play orders, ranging from straight patterns to algorithmic, generative ones. MIDI & CONNECTIVITY SETUP 1. Open the Config menu.
