The One comes equipped with three potentiometers for adjusting volume and pitch as well as selecting samples. A button allows the user to trigger sounds directly at the front panel. For controlling the module via other circuits, there are CV and gate connectors. Thanks to several modes of operation, the inputs can be utilized for a variety of tasks. (See below) Micro SD Cards are used to load audio data into the sample player. A storage medium can hold up to 256 WAV files in 16 / 24 Bit mono format plus configuration data for the CV and gate inputs. Cards are interchangeable during playback. Latencies can be as low as 0.25 milliseconds.
The One is delivered with the VCTRS, a Micro SD Card containing 60 Samples created by the well-known sound designer Ivo Ivanov a.k.a. Glitchmachines. To give users the highest flexibility possible, each audio file comes in three resolutions. (48 kHz, 64 kHz and 96 kHz) Additional sample libraries are sold separately. Of course, the musician is also able to create own sound banks using empty Micro SDs.
The CV modes:
Quantized Pitch – The default setting on One. Incoming CV signals are processed via a quantizer algorithm to fit the equal tempered Western scale. The usable range is approximately 3.5 octaves. The sample rate determines, how far audio material can be pitched up and down. Two examples:
Sample rate: Upward pitch: Downward pitch:
48 kHz +12 semitones (1 octave) -30 semitones (2,5 octave)
96 kHz 0 semitones -42 semitones (3,5 octave)
Free Pitch – In this mode, the quantizer algorithm is inactive, meaning the pitch can be adjusted with a finer resolution.
File Select – This CV mode allows the user to influence the sample selection instead of the pitch.
The trigger modes:
Trigger – This is the default mode with the lowest latency possible. As soon as the module detects a positive trigger pulse, it plays back the selected sound. If a new control signal comes in while One is still at work, it will retrigger.
Fade – Similar to the trigger mode, but with fade in and out at the trigger point to remove clicks.
Gate – In this mode, the One will play a sample as long as there is a positive gate signal. Fades prevent the module from generating clicks.
Looping – While this mode of operation is active, the One will start playing the selected sample in a continuous loop as soon as a trigger pulse is detected. To stop the module, a new sound has to be selected.
Micro SD Cards must meet the following requirements to be compatible with the One:
- SDHC, not high speed cards for video
- 32 GB or less
- FAT32 respectively MS-DOS format
- Master Boot Record (MBR)
Tiptop Audio recommends Micro SD Cards from SanDisk, Kingston, Fuji or Lexar.
