Most of the following description applies to the normal One as well. Differences are highlighted.
The TG-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. Audio files with a length of one hour or more aren't a problem for the module. Tiptop Audio took a pass on extensive artificial processing. - What you put in is what you get out.
Instead of the VCTRS sound library, TG-One features two micro SD cards filled with samples made by Throbbing Gristle. The files were processed by sound designer Chris Carter. One card contains 128 percussive samples, the other holds 128 long audio snippets and loops.
The CV modes:
Quantized Pitch – The TG-One's default setting. 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:
48 kHz sample rate
Upward pitch (max): +12 semitones (1 octave)
Downward pitch (max): -30 semitones (2.5 octaves)
96 kHz sample rate
Upward pitch (max): 0 semitones
Downward pitch (max): -42 semitones (3.5 octaves)
Free Pitch – In this mode, the quantizer algorithm is inactive, meaning the pitch can be adjusted in a higher 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 TG-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 TG-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 TG-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. A new feature: With additional triggers after the playback command, it is possible to make the TG-One jump to random positions in the audio file. This results in cool glitch effects.
Sequencer – While the One plays the next sample of a previously created file list with each incoming trigger signal, the TG-One chooses audio snippets randomly. - Aleatoric rhythms par exellence.
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)
