The 2.x series of Vascular is about consolidation: smoother workflows, stability, bug fixes, better generator engines and better DSP performance throughout.

NEW
polylog (palette: synths)
An analog polysynth in the classic eight-voice style.
- Two oscillators with sync and cross-modulation, noise, a 2-pole or 4-pole filter, two envelopes, an LFO, unison and its own voice allocation.
- Ten kinds of sound on its sheet: pad, strings, brass, lead, sync, bass, pluck, keys, pwm and texture. Its die deals a new design of the kind chosen.
- Eight sliders: cutoff, resonance, envelope, attack, decay, release, detune and motion.

- Synths (palette, first tile): holos, resurgent, bayarea, poundhard and polylog together in one category.
- Twelve starting sessions, in the nzimas folder in settings > sessions: melodic, rhythmic and abstract.
- Session folders (settings > sessions): make a folder with the folder button under the list; rename or delete folders and sessions with the pencil and bin beside each. The save dialog takes a name and a folder, and asks before replacing a session of the same name.
- Node presets: save and load buttons on every node's sheet, with presets shared by all sessions.
- Generators play by themselves: gen rhythm and gen melody beside the loop length on every generator's sheet; the die in the top bar changes the sound only.

AUV3 PLUGINS
- Instruments play their own part: drone or clock, gen rhythm and gen melody, an octave switch, loop length and clock division in the sheet's top bar.
- A randomize die for every plugin instrument and effect.
- The plugin lists in the palette have a search field and sort by name or developer, a section per developer.
- The lfo controller (palette: controllers) moves a plugin's parameters, up to six LFOs a node.

PLAYING
- On the clock, pads and strings swell into each step and fade out; gen rhythm gives them a slower clock division.
- Height means volume all the way: a node against the top bar is at full volume, and position reaches a hard pan.
- Effects arrive 62% wet, so a new processor is heard at once.
- Each patch from create picks its own key and scale.
- Nothing generative moves pitch: no drift and no glide.
- The abstract create path is unclocked, with drifting gates, and sometimes led by a holos.
- fugitive (palette: controllers) plays an octave lower.
- fx sequencer: clear all, left of done.
- On iPhone, sheets scroll when they do not fit.

REBUILT
- A broad pass over the generators and processors: many rebuilt or retuned so that every control is audible, filters and resonators have more character, and the harshest sounds are tamed.
- Bit crush (master effects, hold the mute button): crush and downsample are heard, more toward the top.
- recursive and impulse are retired.

FIXES
- Node positions are kept when a session is saved.
- Joining a metabolism controller to a cluster no longer crashes.
- A die no longer changes a node's rhythm.
- Omega and Blofeld designs are as loud as their presets.

NEW NODES
- AUv3 plugins (palette: AUv3 plugins, beside controllers): host your own instruments, effects and MIDI plugins as nodes on the canvas, their settings kept with patterns and sessions. An in-app purchase; Restore Purchases is in settings > purchases.
- resurgent (palette: generators > macrosynth): a full synthesizer with two scenes, three oscillators, two filters, envelopes, LFOs and effects. The categories on its sheet steer what its die deals.
- bayarea (palette: generators > macrosynth): a West Coast synthesizer, struck or droning.
- poundhard (palette: generators > macrosynth): an FM drum voice with kick, snare, hi-hat, clap, tom and metallic, industrial and glitch kinds, and three dice: the sound, its LFOs and gen rhythm.
- dodgems (palette: controllers): cars bouncing round a court for each voice; every wall they hit is a note.
- metabolism (palette: controllers): a Game of Life for each voice, a playhead sweeping it.
- dial (palette: controllers): a shift register for each voice, up to six. A loop of bits turns a step at a time and its newest bits choose the note: locked it repeats, loosened it drifts, at the middle every step is new. Tap a bit to flip it.

PLAYING AND EDITING
- Solo (mixer button, then hold a node): the node is heard alone with its chain. Hold it again to bring the rest back; a tap still mutes.
- A padlock beside every parameter: a locked parameter is left alone by the randomizer and by every LFO.
- rnd x-y (top of a node's controls): while it is on, "pos x" and "pos y" boxes beside each parameter choose which parameters the node's place on the canvas moves. The box beside each slider is now labelled "invert".
- Edit method (settings > sessions, at the bottom): a tap on a node randomizes it and the edit button opens its controls, or a tap opens its controls and the edit button is not shown.
- Rename a session: in settings > sessions, hold its name in the list on the left.
- metaseq editor: "clear notes" empties the piano roll in one go.
- The lfo button is lit while the node's LFO runs.

RANDOMIZER
- Create is calmer: melodic patches have up to three voices, mostly acoustic instruments; abstract patches are textural; rhythmic patches are percussion only, all on the clock, with a kit under drumaqueen.
- Expand grows mostly effects, in gentler steps from simple to complex.
- Dismantle: takes nodes off the edges of the network without silencing anything else.

CHANGES
- A kick's side chain pumps hard on every hit.
- Rhythmic gates come in many more patterns.
- Rebalance (top bar) spreads the outputs evenly across the whole stereo field and leaves levels alone; it has a new icon.
- drumaqueen plays any generator, macrosynths included.
- A controller now plays the 303.
- A kick is no longer joined automatically to a node you add.
- The palette no longer shows an "anything" tile inside each category.

FIXES
- Muting a processor silences it instead of letting the sound pass through.
- A node that runs away can no longer leave the whole instrument silent.
- The lpf18 processor no longer howls on its own at high resonance.
- gsm no longer leaves a tone ringing after stop.
- Angiogenesis never removes a controller's connections.

NEW
- drumaqueen (palette: controllers): a drum pattern controller in four styles (IDM, rhythmic noise, experimental, breakbeat), with odd metres, polymeter, fills and breaks.
- Microtonal scales (settings > sessions > microtonal): import a Scala (.scl) file to replace the session's scale.
- Chromatic scale, first in the scale list.
- Side chain amount: a kick wired into another voice shows a small box halfway along the vessel; tap it to set how deep it ducks.

CHANGES
- The master compressor (hold the mixer button > compression) is rebuilt: it compresses the whole mix, with a sidechain filter, a kick key, a gain reduction meter and a list of profiles.
- 6-op (generators > fm) plays two octaves higher and starts on the clock.
- Randomizer > wiring no longer moves controllers' connections.
- metaseq and drumaqueen have their own node icons.
- With no session loaded, the app starts in A minor.

NEW
- spool (palette: processors > glitch): a tape loop that records at the speed it plays. Material overdubbed at one speed plays back at another pitch; slow speeds record at a lower rate and alias; reverse records backwards. Pitch steps in fifths and fourths from a quarter speed to twice, forwards or backwards. Mode sets clear, stop, play or overdub; length sets the first take in beats.
- fickle (palette: processors > delays): a tempo delay. Left of centre, the repeats reverse, jump back or shift an octave at random on the beat; right of centre, the repeats rise an octave into a reverb. Chance sets how often, freeze loops the last repeats in time with the beat.
- wavetable (palette: generators > basic): seven wavetables of 33 frames each, through a resonant low-pass/high-pass filter with its own LFO up to 65 Hz, a delay and reverb, and drive. Moving the frame scans through the table with short crossfades.
- fugitive (palette: holos · controllers > controllers): an arpeggio played as a fugue. Join it to up to six generators or acoustic instruments: the first plays the arpeggio, each one after answers it with its own speed (¼× to 4×), direction, transposition in the session's scale and octave, plus ratchets, short loops, grace notes and echoes. Each voice has a tab; "randomize all" draws a new arpeggio and new voices, held it returns every voice to the arpeggio in unison.
- lfo (palette: holos · controllers > controllers): a controller that moves parameters. Join it to up to six generators, processors or holos; each gets a tab with three LFOs (parameter, waveform, depth, rate from 100 s to 40 Hz) and its own randomize. While joined, a node's own LFO stands aside.
- Palette search: a field at the top of the palette finds any node by name, description or category, and says where it lives.
- Randomize button in every node's sheet, in its top row. On processors, holos and drones it draws new settings; on clocked and sequenced voices a new rhythm, line or harmony.
- Randomizer: lfos and motifs. Holding gates, lfos or motifs removes what they dealt.

CHANGES
- The palette is alphabetical inside each section: categories and the nodes in them. Processor categories are now filters, delays, modulation, glitch, reverb, spectral, resonators, distortion, pitch & shift, convolution and grains.
- The lfo button in a node's sheet now has a die: a tap draws a new modulator, a hold removes it.
- Clearing anything (LFOs, gates, motifs, the gesture looper, the canvas, an fx lane) shows a short message saying what was cleared. Tapping the canvas while delete, edit or mute is on says which mode is on. Dice glow when rolled.
- freeze (processors > spectral) fades out when the transport stops and back in when it starts.
- voice (generators > sustained) now sings its note as a clear pitch.
- chamber (processors > reverb) is now a small live room with denser, cleaner reflections.
- Tutorial: the mute step unmutes the node and leaves mute mode before moving on.

FIXES
- Crackle on generators carrying the sub-octave layer, heard on squine among others.
- Changing the root or scale no longer resets the tempo.

NEW
- Rebalance: a new button between the mixer and the patterns button. A tap spreads the audible outputs evenly across the stereo field and, while playing, moves the sources up or down to bring the chains to a similar level. The patterns button now sits beside it.
- Metaseq editor: a second tab in the metaseq's sheet shows its melody in a piano roll. The metaseq is in the palette, in the first row, beside holos. Tap to add or remove notes, drag to move them, drag a note's end to change its length. A playhead shows the current position and notes light up as they play.
- Angiogenesis pause: hold the angiogenesis button while it runs to pause it and store the result as a pattern. Tap to continue.

CHANGES
- While angiogenesis runs, the randomizer's transform and expand work without ending it; create is unavailable. Stopping angiogenesis still returns the canvas to where it began.
- The memory generator (palette: generators > granular) can no longer be the first sound on the canvas, as it only plays back what other voices make. It now has a paler orange.
- The global filter in global steering now includes the 303.

FIXES
- AUv3: Vascular now follows the host's beat position, so it stays in time with other plugins, including after the host's transport is stopped and restarted.
- Acoustic instruments and holos phrases now play in time with the rest of the grid.
- AUv3: reopening a host session now restores Vascular with sound. Previously the saved nodes came back silent.
