What’s New Version 4.2

Fixed a bug introduced in last version that messed up the loop recording on some phones that also messed up the UI connections. (Sorry bout that!) Also, as this app was released before Apple's IOS files app was introduced, it used an old system of iTunes file sharing. That has now been removed and instead your loops can be all saved in 2XB303 iOS Files folder, also incrementally the Export section . You can keep them stored in there for later if you have a nice sounding loop you want to keep. You can access them in iOS Files to copy , paste , rename etc. Also fixed some other bugs

Description

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.

Build 875175829v4.12025-05-30 12:32:04
Improved UI fo iPhone mainly (easier to read)
Build 875071217v42025-05-29 00:37:36
Added saving of auto pad sounds settings to each pattern. Updated core code improved loop better interruption crash other crashes and UI fixes
Build 852050976v3.22022-09-06 20:30:51
Fixed a bug where pitch wasn’t playing on step edit while it wasn’t running. Changed program loading so if it sees an empty slot, it doesn’t do anything. It will keep the current program. Before it crashed the memory loading silently even though it didn’t ruin the saves.
Build 843553817v32021-08-11 23:46:12
It has been a while since this was updated so I hope you enjoy some of these updates and added features. Updated Audiobus Updated Ableton Link (includes remote start/stop) Fixed audio level on channel 2 being louder Balanced audio for drum sounds on metronome drum backing Fixed Note On and Note Off from MIDI so this should hold note with a glide Added Midi control of transpose using chosen channel. (Found in Settings/Midi) Added Sequence Trigger from transposing with 2XB303 or MIDI (Found in Sequence/Control) Added a new AutoPad sound layer that uses first note it finds in Channel 1 sequence to play a selected pad sound as backing track. (Found in Sequence/Control, On//Off and Sound 1-22). You can adjust volume in Mixer section. This can give some great results used with transpose in Control section. Increase screen space for MIDI ports Allowed editing of step while running. Just use counter -/+ buttons, in Edit mode and it freezes selected step to where you move to. Resumes following sequence by pressing Edit Menu again. Add Info links etc like other apps - email link and video demo link Auto initialise empty memory slot as it was confusing before keeping the older program loaded.
Build 830393344v2.22019-02-23 16:53:53
Added support for Bluetooth headphones and speakers. Previous updates: Too fix a possible conflict in the Audiobus and Inter-App-Audio nodes. This could cause the nodes from not showing up or behaving properly in some apps. Last update: A consolidated list of app updates all rolled into one taken from the sister app 6X806 Noise Drum Synth: BPM increments now give increments of 1 for single tap or 5 with a double tap. Captured audio loops exported to Audioshare and Email now adds BPM and date/time to file name. Better dial control: Now you should be able to swipe up and down the knob levels quicker while maintaining refine control. It also snaps to min/max levels instead of wobbling. INIT button for quickly clearing the currently loaded pattern to start a fresh program. Found in System/Settings. Minor update to the UI to bring style up to date with 6X806.

Build 830251491v1.92019-02-12 01:34:45
Fixed the swing/shuffle effect: This never quite worked well as it sometimes cancelled out some glide notes. Finally, this has now be rewritten so it just works. Now you can get those groovy shuffle swing patterns. Swing amount is a global setting found in the main sequencer/sequence menu. This also affects the backing beats.
Build 830238251v1.82019-02-09 16:33:12
Some efficiency changes in code. Removed the input channel for use as Audiobus filter (This broke on many devices anyway and was unreliable)
Build 830223832v1.72019-02-07 23:45:42
Some optimisation.
Build 829362171v1.62018-11-22 15:27:23
1: Changed the way the dials work: Instead of jumping instantly to where you touch, you can now smoothly turn the dials by moving up and down the screen after the initial touch on the dial you want to adjust. Also, if you double click the dial, it will snap to either of three nearest points (start, mid-point and end) which is handy for resetting to default positions. If you preferred the original touch to point method, you can choose that way in the settings/system. 2: Moved WAVE shape dial to quick access buttons. 3. Fixed an issue where clicking to open the Ableton Link settings view for the first time would interrupt the main audio processing thread.
Build 828432529v1.52018-09-12 19:23:02
Fixed an audio bug on iPhone X
Build 828123786v1.42018-08-15 22:41:55

Added Midi Note out. Now Channels 1 and 2 send MIDI note data to respective channels.
Build 827874625v1.22018-07-14 07:31:52
Improved contrast. Previously it was a bit "dull", especially in daylight. Made knobs a bit more "knobby" and less "jumpy" Added a knob helper for fine adjustments. Tap the knob and swipe up and down the screen for finer adjustment of the current knob.
Build 827769231v1.12018-07-05 20:13:04
Added support for Audioshare. Now you can easily export to Audioshare with one button for easy sharing of your audio recordings between apps and tools like trim/normalize Fixed some bugs and made some other minor changes.
