Nota Sampler

Nota Sampler plays a single audio sample across the keyboard. Drop in a sound, set the start/end and loop, and shape it with pitch, an amp envelope and a filter — the built-in way to turn any recording into a playable instrument.

Overview

Load a sample by dragging it from the browser or Finder onto the track (an empty Sampler shows a “drop a sample here” prompt). Each note plays the sample, pitched from the root you set. Trim the playback window, add a loop for sustained notes, and shape the tone with the envelope and filter.

This is the single-sample engine — one sample per Sampler (multisample zone mapping is out of scope).

Interface

The card (mockup 2o) is a live strip over a tab rail.

• Live strip — VOL, PAN and CUTOFF plus the VOICES mode (Poly 16 · Mono · Choke), reachable from any tab.
• Tab rail (left) — Sample · Pitch · Env · Filter.

The tabs:

• Sample — the waveform with draggable start / end and loop handles, the LOOP mode (Off · Fwd · Ping · Rev), a loop XFADE, and Snap zero (snaps markers to zero-crossings); an amp-envelope rail sits on the right.
• Pitch — Transpose and Detune, the root note, and a mini keyboard.
• Env — the amplitude A/D/S/R with Vel → Vol.
• Filter — type (Off · LP · HP · BP) with Cutoff · Reso · Key Track.

Parameters

Parameter	Range	What it does
Volume / Pan	—	Output level and pan.
Voices	Poly 16 · Mono · Choke	Voice mode.
Start / End	0–1	Playback window in the sample.
Loop	Off · Fwd · Ping · Rev	Loop mode (forward, ping-pong or reverse).
Loop Start / Loop End	0–1	Loop points within the window.
Loop Xfade	0…200 ms	Crossfade at the loop seam.
Root	note	The note at which the sample plays back at its original pitch.
Transpose	±24 st	Coarse pitch shift.
Detune	±50 c	Fine pitch shift.
Attack Decay Sustain Release	ADSR	Amplitude envelope.
Vel → Vol	on / off	Velocity controls level.
Filter Type	Off · LP · HP · BP	Filter shape.
Cutoff / Reso	—	Filter frequency and resonance.
Key Track	0–1	How much cutoff follows the keyboard.

Tips & recipes

• Sustained pad from a one-shot: set Loop to Fwd, place the loop points in a steady part of the sample, and add a little Xfade to hide the seam.
• Clean edits: use Snap zero so start/end/loop markers sit on zero-crossings and don’t click.
• Reverse hit: switch Loop to Rev (or reverse the whole sample) for swells and risers.
• Tune it: set the root to the sample’s actual pitch so it plays in tune across the keyboard.
