S-4 changelog

 

S-4 OS v1.2.2 Hotfix

December 9 2024

Bugfixes

• Improved project buffer handling for long samples, enhancing overall loading stability
• DEFORM: Fixed an issue where the DECAY parameter remained static and could not be adjusted

Known Bugs

• While the improved buffer handling resolves some of the project load issues, it does not fix corrupted projects on save. Stay tuned for a completely revamped save system.

Changes in S-4 OS v1.2.0

November 4 2024

Features

• TAPE: TRIM action
  Samples can now be trimmed within the TAPE device. Use [CTRL] + [TRIM] to trim the sample within the loop region set by START and LENGTH. Trimmed samples are saved within the project and can be saved as a file using the [CTRL] + [SAVE] action to use elsewhere.
• TAPE: Adding length to buffer
  Extending the LENGTH beyond the sample length in TAPE adds silence to the end of the sample.
• TAPE: STRETCH mode
  This new mode retains the pitch of a sample regardless of TEMPO and global BPM, replacing the KEYLOCK action in TAPE. In STRETCH mode, PITCH can be offset freely, and GLIDE can be applied. STRETCH mode lives alongside the SYNC and FREE modes, and can be selected by pressing and holding the encoder for the TEMPO parameter.
• TAPE: DENSITY parameter
  DENSITY controls grain size and rate for playback in TAPE. When TAPE is in FREEZE, DENSITY can be used to control the size of the frozen area, and in STRETCH mode it can be used to tweak the sound the loaded sample. It can also be used creatively with modulation. The DENSITY parameter is found on page two of the TAPE device.
• MIX: Revamped DJ filters
  The DJ filters on the MIX page have been revamped to provide a smoother response.

Enhancements

• Significant DSP optimisation, reducing overall CPU load
  This includes increased performance when using POLY and MOSIAC together and when using the S-4 as an audio interface
• Improved clock-in stability
• Confirmation pop-ups added for CONFIG actions
• Added option to reset device
  Under CONFIG → SYSTEM, there is now an option to do a factory reset of the device
• Changed default modulators in new projects to RANDOM, RANDOM, WAVE, WAVE
  
  
• TAPE: In FREE mode, recording no longer quantises the start and stop of RECORD
• POLY: Added fade time to voice-stealing algorithm

Bugfixes

• Fixed an issue with audio buffers not clearing when loading projects, which could cause saving/loading issues
• Fixed an issue where the S-4 became unresponsive after repeated saves and loads
• Fixed an issue where long recordings could cause the S-4 to crash
• Fixed an issue where CC control of time-based parameters didn’t follow the parameter’s quantisation settings
• Actions without text no longer get highlighted when tapped
  
  
• TAPE: Fixed an issue where overdubbing caused audio distortion
• TAPE: Fixed an issue where initial overdubbing in a new project caused clicks and audio ducking
• TAPE: The LENGTH parameter now instantly updates after START is moved towards the end of the sample
• TAPE: Fixed an issue where the buffer length extended incorrectly while looping remained correct
• TAPE: Fixed an issue where TAPE didn’t reset correctly after loading a project with TAPE in FREE mode
• TAPE: Fixed an issue where TAPE in FREE mode didn’t reset correctly after reboot
• TAPE: Fixed an issue where the loop region shifted when LENGTH was set below START
• TAPE: Fixed an issue where configuring LENGTH could cause S-4 to freeze or crash
• TAPE: Fixed an issue where changing START or LENGTH to a larger division didn’t snap to the nearest division
• TAPE: Fixed an issue where moving START all the way to the right in FREE mode caused audio to stop
• TAPE: Using [CLEAR] + [DEVICE] no longer stops TAPE playback
• TAPE: Fixed an issue where buffer dirty indicator (“*”) didn’t appear until re-entering TAPE
• TAPE: Fixed an issue where START became negative after loading an old project and creating a new one
• POLY: Fixed an issue where certain sequencers caused POLY to trigger notes twice

A special thanks to our beta testers for helping us with testing and giving feedback on this update!

Changes in S-4 OS v1.1.0

September 6 2024

Features
