A tank for the notes you play.

Hopper catches every note you play and drops it into a tank. The tank drains in time — one note per step, at a musical rate — so a chord you hold becomes a line, a fast flurry becomes a steady stream, and a phrase you played once keeps coming back out in whatever order you choose.

Three ways to work with it:

• Direct — the tank is a rate limiter. Play anything and it comes out at your chosen rate, the flurries evened out, the gaps filled.
• Accumulate — the tank fills while you play and stays put. Tap Play to let it run, hold Play to spill only as long as you hold it.
• Threshold — set a level line in the tank and play. When the pile reaches the line, the tank tips out on its own.

Choose how it empties

Notes leave oldest first, newest first, lowest first, highest first, at random, at random without repeats, or alternating from both ends. Switch to Loop and nothing is consumed: the tank keeps circulating what it holds, with a playhead running up the pile so you can see it. Chords can leave whole, strummed or one note at a time.

Two engines and a set of dice

The SEQ engine drains at one rate. The PATTERN engine walks eight segments, each with its own rate and note count, for pulses that shift and settle. On top of either, Pressure bends the rate with how full the tank is, and the stochastic rate section rolls dice every few notes to jump the rate a step or three up or down, for as long as you set — with the odds in your hands, weight by weight.

Everything in view, everything patchable

The tank display shows the pile slot by slot, chords as solid blocks, the note just drained, the threshold line you can drag, and the loop playhead. The activity strip shows the dice rolling before they land. On the back: 13 CV inputs for play, flush, threshold, rate and nine more modulation targets, plus 52 automatable parameters and 21 patches to start from.

Specifications

• Device type: Player (note player), 4U
• Tank: 25, 50 or 100 slots; each captured note takes one slot
• Trigger modes: Direct (rate-limited pass), Accumulate (tap to latch, hold for momentary), Threshold (fires when the fill reaches the level, sustains until empty)
• Threshold: 0–100%, set by knob or by dragging the line in the tank display; double-tap to reset
• Drain orders: FIFO, LIFO, Random, Random without repeat, Ping-pong, Pitch up, Pitch down
• Consume or Loop: Loop drains without consuming, with a circulating playhead shown in the tank
• Engines: SEQ (single rate) or PATTERN (8 segments, each with 1–8 notes, its own rate and an on/off switch, with a playing lamp per segment)
• Rate: 12 values from 1/1 to 1/32 including dotted and triplet; free-running or quantized to the transport grid
• Gate length: 5–100% of the step
• Pressure: tank fill bends the rate up to ±3 ladder steps at full tank, in either direction
• Stochastic rate: roll every 1–16 notes, probability 0–100%, excursion 1–5 notes, with separate weights for −3, −2, −1, +1, +2 and +3 ladder steps
• Chord capture: grouping window 0–50 ms; chords leave as Split, Chord or Strum, with adjustable strum spread
• Velocity: As played, Fixed, Scale (0–200%) or Random spread
• Transpose: −24 to +24 semitones
• Emit probability: 0–100%; skipped steps still consume or advance the playhead
• Overflow: Replace (drop the oldest) or Freeze (protect what is stored)
• Thru: hear your playing alongside the tank; in Direct mode, Thru on passes notes through untouched
• Flush: empties the tank and closes all held notes, from the panel or from CV
• Displays: tank column with per-slot fill, chord blocks, threshold line, loop playhead, count/capacity and drained-note readout; stochastic activity strip with countdown, roll lamp and live offset
• CV inputs (13): Play, Flush, Threshold, Rate, plus bipolar modulation for gate, chord window, pressure, emit probability, transpose, strum, velocity, drain order and stochastic probability
• Automation: 52 parameters via MIDI CC, Remote and Combinator, in seven target groups
• Patches: 21 in 7 categories, from basic echo tanks to pattern, generative and performance setups
