Punk Syn Gen A 6 channel pattern groovebox and guitar riff generator for creating heavy rock, thrash metal, punk, and goth style sequences and loops. HEAVY METAL! Create mysterious 80s dark metal loops or create random riffs and drum loops with bass guitar licks. With 2 dedicated guitars, bass, synth and also drum tracks. Whether you play the guitar or not, use this app to come up with new ideas, ideas that you would never have dreamed of. ROCK ON! You can use this app as a guitar riff generator to make whole interesting goth or punk /thrash style sample loops. Every track has independent effects, filter, tuning and ducking ( similar to side chain compression) Generate, modify or manually enter riff patterns with "power" levels. Many different ways to generate or modify patterns that intelligently conform the patters for each instrument. Adding a note manually is easy. Place a note and adjust the power level from small strum, to powerchords for guitars. Power level in Guitar 1 allows you to add single note, single muted or power chords to create thrash riffs. Power level in synth gives you different pad type sounds. Two duplicate drum tracks with some basic drum kit sounds to give you some backing Bass Guitar power level goes from soft touch to slap bass. You can simply generate all day long with one button and it will create a scale, and riffs for every track. If you like the pattern but not the notes, choose your scale and rescale one or many tracks at the same time If you dont like the riff, shuffle it If you want an arpeggio but using a riff, make a riff pattern then press arpeggiate, cycles through arpeggio modes You can freely transpose the entire composition You can play one bar at a time or chain up to 4 bars Half or quarter the playback speed independently on each track so 64 steps plays slower equivalent to 256 steps. Thrash algorithm patterns have been influenced from bands like Metallica and Faith no More. In Fact Faith No More inspired us to use synth strings. Create ideas you wouldn't think of using scales and riffs. Whether you are a fan of Metallica riffs or punk, you can never tell what you'll get when it generates all tracks. Some chaos is also added to the generation of riffs. Many affects can be added from purposely adding bend, echo, reverb, extra distortion for even more thrash metal sound and resonating low pass filters to create mysterious and moody goth style patterns. This app is part of a family of apps: 6x808 - a drum sequencer, 2xb303 a TB303 sequencer, 7XdXfm - a 7 track-4 operator FM synth, 7XWave - a sample manipulation groovebox. Unique to this, the step edits are removed, and replaced with a dedicated piano roll for placing notes in a grid representing pitch and time. Like all the other apps, MIDI is included for sync as well as Ableton Link and Inter App Audio so you can route the audio to Audiobus/AUM Output note data on each channel too. You can sample whats playing anytime and it will record a sampled loop you can export to Audioshare or clipboard/email

NEW IN 5.0 — PLAY, PRACTISE AND CONVERT - Instrument voices: every part plays with a voice chosen by its General MIDI program family (piano, organ, guitar, bass, strings, brass, winds, synths) and channel 10 plays a drum kit. The voices are Midiary's own sounds; they sketch the arrangement rather than reproduce a General MIDI sound set. - Practice & mix: mute or solo any part, change speed from 25% to 200% without changing pitch, shift the key up or down 12 semitones for singers, and loop any range of bars. - Play to MIDI gear: send the file to a USB or Bluetooth MIDI keyboard, module or interface, with its own program changes. SysEx is sent only if you turn it on. - Key and chords: an estimated key and a chord for every bar, with a shareable chord chart. Tap a bar to play from it. - Lyrics and karaoke: lyric events and .kar files follow playback line by line. - File tools: convert format 1 to format 0 for keyboards, arrangers and player pianos, or split a file into one track per channel for your DAW. Set or scale the tempo, change resolution, set a channel's General MIDI instrument, rename, move or delete tracks. Every change is verified and undoable. - Extract: copy a range of bars and the parts you choose into a new MIDI file, with tempo and sounds set up at its start. - Audio export: render M4A or WAV with the current mix, key and speed — a practice backing track in seconds. - Bars and beats throughout: event list, note list, piano roll grid and a playhead. - Open MIDI files from Files, Mail or other apps, use Shortcuts actions (file info, format conversion, transpose, tempo), and iPad keyboard shortcuts. Midiary is an offline studio for Standard MIDI Files on iPhone and iPad. Your imported original always stays intact. MAKE MUSICAL CORRECTIONS Select tracks and channels, transpose, adjust velocity, or move note starts toward straight and triplet grids with variable strength. Drum protection keeps channel 10 out of batch edits. EDIT THE EXACT NOTE Search by pitch, filter and page through long files. Change a note's pitch, velocity, start and duration. Review the actual changes before saving; ambiguous overlaps and unsafe edits are blocked with an explanation. GROOVE BENCH Extract the timing and velocity feel of a passage and apply it to another part with separate timing and dynamics strengths. Up to 64 templates are kept on the device. KEEP THE ORIGINAL Imported MIDI bytes stay unchanged. Edits save locally with undo and redo that survive closing the app, up to 20 steps within 48 MB. Restore the original as an undoable step. Damaged sessions are preserved for recovery. INSPECT THE FILE Tracks with their instruments, channels and note ranges; tempo map; time and key signatures; markers; structural findings; a channel-coloured piano roll; and an event desk with bar, time and tick. Metrical and SMPTE timing and format 2 sequences are supported. EXPORT YOUR WORK Share the untouched original, the edited MIDI, a cleaned copy with missing End-of-Track events added and hanging notes closed, an event CSV, or rendered audio. Start with your own .mid, .midi or .kar file, or open the bundled piano sample or the band sample with lyrics. Imports support up to 8 MB, 1,024 tracks and 100,000 events. Playback runs in the foreground. No account, subscription, in-app purchase, advertising or tracking. Files and editing sessions stay on your device unless you export or share them. Midiary does not record from the microphone. Bluetooth is used only if you open Bluetooth MIDI pairing.
