A creative bass synth sequencer for creating electro melodies or dirty phat & funky pure acid techno 303 style basslines. With LIVE CONTROL feature to trigger and transpose both sequences and new synth pad layer. Record and export your audio loops. Inspired by the acid house music scene. An IOS exclusive, compared to a modern equivalent to Rebirth (Rebirth was a popular tb - 303 clone a decade ago). Look at the video tutorial for a how-to guide. Listen to what you can create easily with 2XB303. Create electro, house, techno, edm or synth sequences using standard step functions as seen on various sequencers like the Roland SH 101 synthesizer. Built in pad layer than follows pitch. Transpose and trigger sequence even with MIDI Your synth sequences can also be generated randomly, shuffled or modify just notes. Easily capture whatever you hear and export to AudioShare, Audio-Copy, Email or iTunes Shared Folder. Support for Audiobus 3 routing, Ableton Link, IAA (Inter App Audio) Tweaking cut-off & decay Env-Mod & glide & accent etc for that classic sweet-spot acid growl Tap to dials to swipe up & down for fine adjustment of knobs. The sound was first compared to a Cyclone TT - 303 synthesizer & tweaked to extend sound shaping beyond a just bass maker. Waves have optional harmonic version, noise, LFO, glide speed & PHAT/ BASS, and great effects. This is designed to give pure electro music creativity beyond an acid synth 303 bass maker to create dynamically fluctuating overlaying electronic patterns. A good addition to any electro, drum and bass, acid, techno, house and any other EDM fans LIVE CONTROL feature: Use the keyboard for the following cool tricks: [Sequence/Control/Transpose]: Transpose both channels simultaneously while playing. Now ability to trigger sequence too, with synth pad layer. (optional and 22 sounds) [Sequence/Control/Pattern]: Instantly switch to a saved sequence while playing. Keys correspond to stored program numbers, starting from the current program thats loaded (key 1 is your current program, key 2 is current program+1). Highlighted keys show stored programs. This is great for building up live tracks, or instant crossfading between programs. You can also "Hold settings" so it locks settings like effects. MOD: LFO auto control low pass CUT-OFF and/or PITCH. The pitch level can give a vintage synthesiser effect subtly detuning with low SPEED or faster for chaotic random pitches. EFFECTS (Global/master are in yellow.) OVERDRIVE, COMPRESSION adjusts threshold, ratio, & gain. This is a global effect. ECHO tempo synced with feedback & wetness. SAVE ALL. When not playing, save to memory. SYNCING Ableton Link syncs with apps .Enable for precise timing without syncing. Press LINK button at the bottom for settings. MIDI sync with External, Virtual or Audiobus. 2XB 303 can be master or slave. ( any simple class-compliant USB should work but some may need to be power assisted) Virtual MIDI In is always on. If you send from another app AND receive MIDI clock then you will be receiving both MIDI CLOCKS. Choose only one unless you want double tempo (which can be interesting). While Ableton Link is enabled you can send clock. This means you can use one app to control 2XB303 synth alongside external hardware sequencers MIDI note data is sent out on each channel AUDIO Record a fixed length, default to 32 steps. Can be changed in settings. Arming the sampling with CAPTURE (flashing). Starts at counter 1 (ON). PLAY CAP to listen to your super cool sampled acid synthesiser loop. Audiobus 3 and IAA (Inter App Audio) Support. Route audio to mix or record into other applications Audio can be routed via IAA into apps like Apple's Garageband. Garageband will also sync your sequence for excellent multi-track recording. To save you press "Save all", it then flashes. Now choose destination ("!" means its occupied ) then press "Save All" to confirm.

In grand celebration of International Joke Day 2024, we at Caelum used our incredibly intelligent minds to bring you our first sampler; King Key. Gone are the days when you were left begging for high quality one-shot keyboard samples, now you can get King Key. Anywhere in the world you can now play the sounds of a keyboard, on your keyboard. We also blessed you with the sounds of a MIDI keyboard, a typewriter and 4 produced kits as our generosity knows no limits. Click, Clack, Svvvvt, B-ding, cha-cuh, fshhhh. With 9 instruments and 11 presets at your finger tips you can finally be the person your parents wanted you to be, a King Key one. Using proprietary high-detailed sampling techniques, which are sadly too complex for you to understand without demonstrative play-dough, we have captured the essence and spirit of a vintage Imperial typewriter, a Modal Cobalt8X and a Generic USB keyboard. We then took these beautiful, inspirational samples and produced them into some juicy, expressive kits for your pleasure. King Key is designed as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as Logic Pro, GarageBand, Cubasis 3, AUM and Beatmaker 3. King Key also works as a standalone instrument.
