BL-303

BL-303 is a contribution synth with Big Love to the legendary Roland TB-303.

The BL-303 allows you to effortlessly create the iconic acid basslines, leads, and sequences.

Version 3.0 includes improved and resizable user interface, the filter was fine-tuned to sound and behave even closer to the original TB-303, a few more minor performance and sound improvements. Native support for mac Arm and Intel processors.

The sequencer part (including the slide and the accent) is handled with MIDI notes velocity:

• Shorten the note length a little bit, so it ends slightly before the next note (like the TB).
• Use the Velocity to control the Accent and the Slide.
• Velocity 0 – 9: Slide On.
• Velocity 10 – 100: Regular note.
• Velocity 101 – 126: Accent On.
• Velocity 127: Accent & Slide On.
