The Roland JV-1080 is a 64 voice, 16 part multitimbral rackmount synthesizer module in the Roland JV series. It is notable for being one of the most popular synthesizer to be used throughout the 90s, being used in countless pop songs, video games and more. It is a direct successor of the Roland JV-90, however it also borrows a lot of elements from the Roland JD-990 (as well as a few patches).
Notable changes from the prior lineup include an increase of polyphony from 28 voices (or 56 if using a VE-JV1 or VE-GS1 card) to 64 in total, regardless of expansion status. Multitimbrality has also been doubled, from 8 parts to 16 parts. Expansion abilities have been greatly, er, expanded, by including additional board slots on the motherboard, something which would be further increased with its successor. It features 448 unique internal waveforms, up to four can be used in a single patch and each one can have its own WG section, Time variable filter (TVF), Time variable amplitude (TVA). Two tones can also share a signal path in different structures, which can provide additional tone features such as a booster or a ring modulator. It also features a Multi-Effector EFX (or EFX for short) - with 40 different algorithms available, each modifiable to fit the needs of a patch, as well as retaining the reverb and chorus from the JV-90.
In simpler terms, this thing was a beast for 1994 standards, and still is very usable now. It's really no wonder Roland still features sounds from this unit in their contemporary offerings.
Terminology
- Tone - refers to a single unit of sound. Each tone can have its own pitch, filter, amplitude, as well as envelopes to control all of these, and two assignable low-frequency oscillators.[terminology 1]
- Patch - consisting of up to four individual tones, playing at once. Can be saved into user memory and can be used alongside a performance
- Performance - consisting of up to 16 individual patches. Each one may be played independently, at different pitches, panning and volume, and has its own independent complement of CC's and settings.

Editing
There is plenty of software that can be used to edit the JV-1080, such as ChangeIt! and emagix SoundDiver, among other freeware options. The rest of the section will document select parts of a patch in more detail.
Common
Analog Feel
This adds a subtle pitch fluctuation to the waveform, helping it feel more "analog".
Stretch tune
This will make high notes higher in pitch than normal, and low notes lower in pitch than normal, similar to an acoustic piano. The higher the setting, the more pitch is affected.
Priority
Controls how voices are culled if exceeding the 64 voice limit. Last eliminates the oldest voice, with Loudest eliminating the quietest voices.
Velocity Range
This option enables or disables the velocity range of a tone. This can be further configured with the Velocity Range settings.[2]
Structure
There are 10 different types of structure, that configure how two pairs of tones (1 and 2, or 3 and 4) will behave.[2]
- Type 1 is a simple passthrough, providing up to four total independent voices, each with their own filter and amplitude section.
- Type 2 has the first WG (Wave Generator) section go through the first TVA, and then is merged with the second WG (which has not been modulated yet) into both TVF's, ending in the second TVA. Useful for enhancing filter response, according to the manual.
- Type 3 is similar to Type 2, however between the first TVA and the dual TVF, there is a booster section. The booster section acts like a distortion/clipper effect.
- Type 4 is similar to Type 3, with the booster being moved from between the first TVA to between the two TVF sections.
- Type 5 is similar to Type 3, with the booster being replaced by a ring modulator.
- Type 6 is similar to Type 5, but the ring modulator here can be mixed with the dry signal from Tone 2 to dial back the potential harshness of this effect.
- Type 7 is sort of similar to Type 5, however the first TVF is moved in front of the first TVA, right after the first tone's WG has been processed. The ring modulator now sits between the first TVA and the second TVF.
- Type 8 is similar to Type 7, however the dry signal from Tone 2 can be mixed with the ring modulator output similar to Type 6.
- Type 9 has both tones pass through individual TVF sections, but the first tone passes through its own TVA first, then gets ring modulated with the second tone, and then the final result passes through the second TVA.
- Type 10 is like Type 9, but like with Type 6 and Type 8, the ring modulator can be mixed with the post-TVF output of the second oscillator.
