Quick Links

The Stereo Triggered Sampler is a high fidelity, two-channel stereo audio recorder and playback module. The
STS can record high quality stereo WAV files while simultaneously playing two different stereo files. A maximum of
600 samples can be loaded at one time from the removable/swappable microSD card, in a variety of formats up to
96kHz/32-bit/stereo WAV. All sample parameters (1V/oct pitch, sample file selection, length, and start position) are
CV controllable, and trigger jacks for play, record, and reverse allow for synchronization. On-board editing tools
allow you to set loop/trim points and gain, as well as assigning samples to banks and slots.
• Two independent stereo playback channels can play any of 600 samples simultaneously
• Recording channel creates stereo WAV files directly onto microSD Card for immediate use
• Extremely low noise, high fidelity design
• Plays a variety of WAV files up to 32-bit/96kHz
• Intelligent file system makes loading large sample libraries easy by organizing banks into folders
• CV and controls for 1V/oct tracking, Start Position, Length, Sample selection, Reverse and Play
• Trim samples and set Loop points, adjust gain, and re-organize banks and sample slots on the fly.
• Includes microSD card with Sample Pack, SD adaptor, 10-to-16 pin power cable and M3 screws

  • Page 7 Another way to go to an empty bank is with the Bank Rec+Bank trick (see Tutorial 3). Since the STS boots up with the Bank Rec button set to the first empty bank, this is a fast way to immediately jump to an empty bank.

    Start Pos to the current volume setting. When you power-on the STS, the volumes are automatically set to 100%, so that means you have to turn Start Pos all the way up to 100% before the volume feature engages. After that, you can turn the knob down to reduce the volume.

  • Page 12: Sample List Html File

    Your actual sample files will never be changed. We plan to create a guide to editing the index file, as well as making the STS’s text parser a bit more robust in terms of handling human error before releasing a guide to editing it. However, those familiar with config files will probably be able to figure out the syntax easily.

    Hold Edit and turn the right side Scrub Start or Scrub End knobs. The STS will scrub the start or end point of the sample as you turn the knob. The knob is velocity-sensitive, so turning it quickly will scrub a large distance, while turning it slowly will scrub a small amount.

    STS channels with different rhythmic patterns. In Stereo Mode (see p.8) both stereo samples will be mixed together. Each side of the STS has its own CV jacks, so you can treat each side of the STS as an independent instrument, but both draw from the same collection of samples.

    (without modifying playback time). The simplest way to play with granular scrubbing on the STS is to load a familiar sample: a drum loop or a vocal sample, perhaps. For starters, pick a sample that’s between 1 and 10 seconds long.

    In the last group (each bank) the button will be the color and blink of the bank you’re in. You have to save with Edit+Save to have the changes take effect after you power the STS off. If you don’t save, you can hit Edit+Revert+Bank to restore to the latest saved version without having to power down.

    Card Specifications • We include the ideal type of card to use with the STS. If you need to buy an additional card, we highly recommend that you purchase the same class of card. The STS works best with a UHS Speed Class 3 card (also known as U3, which is the fastest of the UHS-I type cards).
