The ADSR voice

Program your own voice the way the original did: an eight-digit code typed on the calculator keys.

ProVerified for version 1.1.0 · Updated October 17, 2026

The sixth position on TONE is a voice you set yourself. There are no sliders: like the pocket synths it comes from, the voice is one eight-digit number, typed on the calculator and stored with M+. Each digit sets one thing, from 0 to 9.

Store a code

  1. Slide POWER to CAL and TONE to ADSR.

  2. Press MC to clear the memory.

  3. Type the eight digits on the white keys.

  4. Press M+.

  5. Slide POWER back to ON and play.

The LCD with TONE on ADSR: the code 61079130 in seven-segment digits, the tempo ♩120 in the corner and the envelope drawn as a line underneath.
With TONE on ADSR, the LCD shows the code and its envelope.

The code stays when you quit and come back. If you never store one, the voice starts as 61079130, the English horn.

A leading zero can be skipped, because the calculator drops it anyway: 453200 is the same code as 00453200.

The eight digits

Left to right. The times are PocketTone's own; the original's manual only says that a bigger number means more.

6Release0 almost none … 9 about 2.4 seconds, a long echo after you let go
7Vibrato0 off … 9 deep, up to a bit more than half a semitone
8Tremolo0 off … 9 deep

The ten waves

  • 0 to 4 are the waves of the five preset voices.
  • 5, Guitar 2, is three uneven pulses an octave down. 6, English horn, is a narrow pulse an octave down. Neither has a preset of its own; you only reach them with a code.
  • 7, 8 and 9, the Electro-Sounds, are the Piano, Fantasy and Violin waves with a fast pitch wobble on top.

Vibrato and tremolo have no speed digit: their speed follows the tempo, so TEMPO▲ and TEMPO▼ make them faster or slower.

Reading the curve

The line under the code is a sketch of the envelope, not to scale: up for the attack, down to the sustain level, along for the sustain (flat when digit 5 is 9, sloping down otherwise) and down to nothing for the release. Vibrato and tremolo are not drawn.
