Teenage Engineering EP-133 K.O. II firmware

no headphone jack? no problem! now you can use USB audio with any class compliant USB audio host to connect your KO2 straight in and send audio in and out of your phone or computer. ko2 supports stereo audio in, as both a sample source and an audio source. as well as usb audio out, to record sound directly into your DAW, or any other class compliant device. just plug KO2 into your phone or computer and select it as an input or output, or both! selpmas esrever nac uoy won! reversing samples is a great way to bring life back to your existing sample library and discover new textures. to reverse a sample, add it to a pad then press (shift) + (sound) to open (sound)(edit), press (plus) until you reach “tim”. rotate the (knobx) knob until “rev” shows on the display. play the sample again and it will be reversed. now you can go back to (main) and make a beat with it. add character and use less storage by lowering the recording sample rate. you can change the sample rate in system settings. press (shift) and (erase) to open (system) settings. press (plus) until you reach “smp” press (enter) and then “rec” will show on the screen. press (enter) again, then use (minus) and (plus) to select between lo, mid and hi sample rates. lo is 26,250khz - which is very lo-fi. mid is 32,000khz - which adds some charater. hi is the standard 46,875khz - which is the standard quality on ko2. if you want any other sample rates you can import samples at any sample rate directly onto ko2 using the ep-sample-tool. 20 seconds not enough? now you can record mono samples up to 40 seconds long. just switch the sample type to mono and the sample time will adjust up to 40 seconds, perfect for extra long samples. to record a mono sample: press (sample), then press choose a mono source with (minus) and (plus) and hold a pad to record the sample to that pad.

- improved audio stability to reduce glitches. - restored SYNC OUT continuous clock output. - fixed: bug fixes and performance improvements for EP SAMPLE TOOL. - fixed: various UI quirks related to faders, sampling, and chopping. - fixed: turned-off LEDs could sometimes glow dimly. - fixed: various MIDI bugs.

new features! - added: Show "disk low" warning message when pressing SAMPLE and there is not enough disk space to record 20 seconds. - added: midi reset all controllers on sequencer stop. this is now system setting 140 (on) and 141 (off). project management - fix: project erase did not reset scenes - fix: Project erase did not reset some pad settings (e.g. MIDI channel). - fix: Swing was not updated when loading a new project. - fix: After loading a project, erasing notes would not enable the undo umbrella. sound editing - fix: With a perfectly timed stop, the sequencer could stop past pattern end. (E.g. 5.1.1 for a 4-bar pattern.) - fix: Only record note repeats for the currently selected group. - fix: For some notes, LEDs were not lit for the full duration. This caused misleading blinks at note-off. - fix: Stuck notes when using punch in fx pad 0. sampling - added: Show "disk low" warning message when pressing SAMPLE and there is not enough disk space to record 20 seconds. - fix: When hands-free sampling 20 seconds of stereo, the device would incorrectly display "FUL" and discard the recording. - fix: Newly recorded samples would inherit settings (like pan or pitch) from the pad's previous state. - fix: faster storage cleanup after deleting samples. - fix: When fixed-length resampling a pattern, start recording instantly, also 
capturing any initial silence. This preserves the timing relative to pattern start. sound editing - fix: Trim in would not always move to sample start. - fix: Small trims would not enable the scissors icon. - fix: The UI did not refresh after pasting a pad. - fix: Keep pad settings when browsing sounds with +/- and returning to original sound. Numpad selection acts as a fresh load. - fix: Pads would leave mute groups when changing sound. - fix: Improved initial
BPM and bar length
detection for samples imported via EP SAMPLE TOOL, especially those with custom sample rates. midi and sync [...]

scenes - Erase Scene ((ERASE)+(mAIN)) Update: Hold for 2s: If the current scene is empty and not part of the song, it is deleted (displays “DEL”). Otherwise, its contents are cleared (displays “CLR”). SONG MODE - changed: stop the song when it reaches end. - changed: when stopping a song, go back to the position where the song was started. - fix: undo while recording could restore the wrong pattern. - fix: pause song progression when LOOP mode is active. - fix: when recording, notes sometimes got quantised to the wrong pattern. - fix: stay in active scene when leaving song mode. - fix: Improved song mode cut/paste visual feedback. sampling - new: allow chopping a sample from one group to another. (Example: Press (groupa), select a sound by pressing pad, press (groupB), CHOP!) - fix: hands-free sampling was allowed on already recorded pads, causing a weird state - fix: hands-free sampling did not stop automatically after 20 seconds. - fix: lag when retaking a sample. - fix: the sequencer sometimes did not stop after fixed-length pattern recording. - fix: in hands-free sampling, prevent changing the fixed recording length using (plus) / (minus) after recording has started. connectivity - new: added system setting MID -> CHN -> OFF (127). When selected, pads only send and receive MIDI voice messages if a MIDI channel is assigned in SOUND EDIT. - new: reduced latency by enabling running status on TRS MIDI OUT. - fix: weird behaviours when recording with external clock. - sync in start did not exit record arm mode. - in some cases, stop did not stop recording and metronome. - fix: Program Change and Channel Pressure messages on TRS MIDI OUT. - fix: OMNI/basic channel MIDI notes were forwarded even if MIDI THRU was OFF. - fix: SYNC24 OUT did not work well with some devices
(e.g. MC-202). - fix: Improved USB reliability when connecting to Windows PCs. - fix: handle unsupported characters when uploading sounds with EP SAMPLE TOOL. sound edit [...]

stack effects, make a beat from a beat or combine samples, all using the new resampler. just hit (sample) then press (plus) until RSP shows on screen. you can then hold (shift), press a pad then press (play) to sample the length of the currently selected pattern. you can even switch groups after you’ve engaged hands free sampling to sample sounds from another group. learn more about resampling here use song mode to chain scenes together. hold main then press (enter) to open the song list editor, you can then view and edit the current song position as well as add up to 99 different song positions. combining that with a maximum pattern length of 99 bars that means you can create songs as long as 9,801 bars! this fight might just need some wraps... learn more about song mode here sometimes you need both hands to play an instrument, and you want to sample it. use hands free sampling and let ko2 hold the buttons for you. when sampling hold (shift) and press a pad to engage hands free sampling. you can then sing, play, shout and strum, ko2 will take care of the rest. once you are done just press sample and ko2 will stop sampling. remember to adjust your threshold and gain and combine hands free sampling with the new resampling feature send your beat back into the ring. learn more about hands free sampling here kick and bass not getting along? sidechain will duck the volume of the bass when the kick comes in. press (shift) and (fx) to open output, then (plus) to switch to sidechain. select the sidechain source by holding a group pad and selecting a sound on the pads, then select the destination groups by holding (shift) and pressing the group pads. dial in how hard they punch by adjusting the length and shape with (knobx) and (knoby) respectively. learn more about midi sidechain here with increased polyphony, ko2 goes from 12 mono/6 stereo sounds to up to 16 mono and 12 stereo sounds.

- double-trigger during quantized live recording. - loop could exit to the wrong position when exiting and entering loop quickly. - prioritize held notes over released notes when running out of voices. - velocity and duration note changes (done with SHIFT + POT) could get lost. - EP SAMPLE TOOL could not restore max length sounds.

- FX + GROUP solo group function did not mute MIDI notes - auto chop improved when slicing long samples - fader recording could erase fader events in other groups - android USB MIDI connectivity resolved - fixes corner case where sound got silent after exiting SAMPLE mode - fixes crash when switching to 'sound 0' while playing - fixes rare sample corruption after removing sounds

- support for new backup/restore feature in EP SAMPLE TOOL - when doubling pattern length with SHIFT + RECORD + PLUS, automatically copy the existing notes. - press SHIFT + RECORD + PLAY to record from pattern start. - press RECORD + ERASE + PLAY to record in overwriting mode. - various bug fixes and UI improvements.
