Fast firmware update
To update Rample:
- put the micro SD inside the SD adapter and insert it in your computer
- drag the "rample.bin" file into the micro SD card (do not change the file name)
- insert the SD card in Rample
- power on Rample while pressing/holding the encoder and wait a few seconds
- please verify the new version number (displayed in the SETTINGS > INFO menu)
Recommendations:
- in case of any problems when running samples (glitches, latency, noisy sounds, save/load sample fail, ...) please read this FAQ entry.

rampleOS 2.00
Feb 15, 2024
Breaking changes
- Latency greatly improved
- Audio effects parameters can be modulated with a faster frequency
- No more audio clics (when playing a sample, when loading a kit, ...)
- Redesigned effect FREEZE: improved the granular algo to make the sound softer and more homogeneous
- Redesigned effect BITCRUSHER: greater range
- Chromatic notes quantizing (for pitch) is now more accurate
- Output levels now in dB instead of using linear volume (allowing a better dynamic when playing samples with a midi controller, where the velocity controls the volume of the sample)
- Parameters START POINT and LENGTH can be set to exponential (for allowing more precise fine-tuning when these parameters are around low values). It's now possible to get very short sample LENGTH to create faster/glitchier sounds (SETTINGS > SLICER > EXP must be enabled).
- CC98 = instant kit number selection
- New vu-meter: INPUTS (displays the cv inputs voltages on screen)
- when holding ASSIGN and selecting a kit to be loaded, this new kit will keep the FX parameters of the previous kit
- New setting SLICER = 1/128 (sample is divided into 128 equal parts, for START POINT and sample LENGTH quantizing)
- FX parameter hook issue when rotating fast a pot
- Assign CV input to sample LAYERS : more precise selection (and last layer now easier to select)
- Fixed crash when playing a 24-bit layer
- When receiving a new CC for changing params, holding a switch was making it momentary
- End of stereo file was sometime noisy
- Kit selected samples layers were lost after a SAVE SETTINGS
rampleOS 1.50
July 26, 2022

- Layers = cyclic, was always starting from layer 2 instead of layer 1
- Mute group was buggy when multiple sample where triggered closely
- Preview sample name when scrolling kits: now displays 'VOID' if no sample found in voice
- Layers = cyclic, can be now reset to layer 1 when double-pressing LISTEN, or receiving a STOP midi message

- Improved low luminosity features on screen
- Improved CLASSIC and WAVED vu-meters
- Code optimization
- new vu-meter: TIMELINE (display the 4 samples playback % progression)
- new setting: FLIP ON/OFF (rotate the screen, useful if you want to flip your Rample in your case)
