This is a list of many custom instruments and sounds created by the OS community.

Rules for GD’s Custom Instrument Archive V2

Inclusivity First This archive is open to all creators. Any instrument may be added as long as it:

Is made in Online Sequencer
Has clear instructions
Has an example sequence

No instrument is removed just because someone dislikes how it sounds.

Reworking Instead of Deleting If an instrument needs improvement:

Do NOT delete it
You may rework or improve it
Credit the original creator
Alternate versions are allowed

Credit Creators Every entry must include:

Creator name
Link to OS profile
Example sequence

Clear Instructions Entries must include:

Base instrument
All slider values
Any special techniques (pseudo‑sustain, layering, etc.)

Respectful Collaboration

No insults
No hostile edit summaries
No deleting entries without discussion
Improvements should be constructive

Experimental Sounds Allowed Stylized, distorted, unrealistic, or unconventional sounds are welcome.

Organization

Keep formatting consistent
Use correct categories
Include images when helpful

Versioning If you improve an instrument:

Add it as “V2” or “Alternate Version”
Do not overwrite the original
Credit both creators

No Gatekeeping Quality is subjective. This archive exists to avoid the gatekeeping issues of the main archive.

Follow OS Wiki Standards

No vandalism
No unrelated content

Instruments

Oboe/Bassoon

Creator: Solea

How to create:

Select synthesizer or create a clone.
Set the waveform to sawtooth
Set the filter to lowpass and set the frequency to somewhere around 1200
Change the LFO to pitch, and set the intensity to 5
click on the ASDR envelope and set the attack, decay, and release to 0. Then, set the sustain to around 0.5.

In advanced options, set Classic Reverb to about the middle of the slider
Click EQ and set the High and Mid EQs to around 20.
Turn the volume down to your liking.

To make the oboe more realistic, use markers to increase the pitch LFO intensity on long sustains.

Ragtime Piano Sustain
