The most significant deficit in the JV-to-SF2 conversion is the loss of real-time programmability. The JV-1080 allows users to tweak filter cutoff, resonance, and envelope times in real-time. In an SF2 file, the sound is "frozen." While SF2 supports filter modulation, the specific character of the Roland TVF (Time Variant Filter) is difficult to replicate exactly using the generic filters found in most SF2 players.

The JV-1080’s signature sound is its RCL (Roland Chorus Legacy) algorithm—a thick, slightly detuned stereo spread. Most SF2 players ignore CC#91 (External Effects Depth). To fix this, insert a Chorus plugin after your sampler. Use these settings: The most significant deficit in the JV-to-SF2 conversion
