The most comprehensive BeepBox mod with 30+ integrated features from the best mods
UltraBox offers the most diverse collection of synthesis engines in any BeepBox mod. From classic chip waves to advanced 6-operator FM synthesis, you have access to a vast sonic palette that can recreate authentic retro sounds or create entirely new timbres.
UltraBox's flagship feature is its 6-operator FM synthesis engine, the most advanced FM implementation in any BeepBox mod. FM synthesis creates complex timbres by using one oscillator to modulate the frequency of another.
Create evolving, animated sounds by continuously changing the width of a pulse wave. This technique was used extensively in classic video game consoles like the Commodore 64.
For ultimate control over your sound, UltraBox offers both harmonic and spectrum editors that let you sculpt waveforms with surgical precision.
All the classic waveforms that defined chiptune music, plus advanced noise generators for percussion and effects.
Transform UltraBox into a full-featured sampler by importing your own audio samples.
Go beyond presets with custom waveform creation capabilities.
UltraBox provides more channels than any other BeepBox mod, giving you the freedom to create dense, layered compositions without compromise. With 32 pitch channels, 8 drum channels, and 12 modulator channels, you can build professional-quality arrangements.
With 32 pitch channels (compared to BeepBox's 8 or JummBox's 16), UltraBox lets you create complex orchestrations without running out of space.
Eight dedicated drum channels provide ample space for complex rhythm arrangements.
Modulator channels are UltraBox's secret weapon for creating dynamic, evolving music. These special channels control parameters of other channels in real-time.
UltraBox includes a comprehensive suite of effects and processing tools that rival professional DAWs. Every effect has been carefully tuned for chiptune music while remaining versatile enough for any genre.
