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

PolyDelay Polyrhythmic Delay Plugin (AUv3) PolyDelay is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand. Overview PolyDelay is a dual delay line / stereo effect with optional host tempo sync. While PolyDelay can be used to create interesting stereo polyrhythmic delays, it can also produce more familiar delay patterns such as dotted eighth and quarter note triplets. Polyrhythms, Divisions and Beats PolyDelay calculates delay times based on a BPM (beats per minute) tempo, and the polyrhythmic notation of D:B, where D = divisions and B = beats. For example, 3:2 would mean that the time for 2 beats should be divided by 3. If you're more use to the idea of note lengths and delay times, such as quarter notes and dotted eighths, etc., this might be confusing at first, but hopefully this guide will help. Firstly, everything starts with the beat! So, for 120BPM, each beat (or quarter note) will be half a second, or 500ms. So if you want a quarter note delay, you want 1 division within one beat, so you would set Divs and Beats to 1. Here are some typical note values, lengths (120BPM) and their D:B values: 1/4 = 500ms = 1:1 (take the length of one beat, and divide that by one) 1/8 = 250ms = 2:1 (take the length of one beat, and divide that by two) 1/16 = 125ms = 4:1 (etc.) 1/32 = 63ms = 8:1 (etc.) See how the divisions are doubled-up for each note? And here are some dotted and triplet note examples - see how the D:B numbers start to get interesting! 1/4D = 750ms = 2:3 1/4T = 333ms = 3:2 1/8D = 375ms = 4:3 1/8T = 167ms = 3:1 A classic stereo delay would be 1:1 (1/4) left, and 4:3 (1/8D) right with Width set to max. If you want a really long delay, a 1:8 setting would give you 4 seconds at 120BPM with Multiply set to Normal, or 8 seconds set to Half. The Presets also include some typical (and not so typical!) examples to get you started. The fun really starts when you start mixing "unusual" (typically odd numbers) divisions and beats, such as 5:4 or 2:7. These sorts of relationships are what we typically refer to as polyrhythms. Try experimenting with PolyDelay on simple sequences and drum parts / patterns and you may start to hear all sorts of interesting rhythmic interplay as your brain tries to figure out what's going on! For additional tone-shaping, PolyDelay includes variable stereo width, a high and low pass filter, stereo modulation and internal limiting to keep audio levels in check.
