PackWhy it exists
A storefront should sound like a session.
Static previews help people inspect a sample. A playable sequence helps them imagine what they could make with the whole pack.
Shape the groove fast
Tune tempo, pitch, gain, envelopes, swing, and bar length from one focused studio surface.
Turn jams into pack interest
Public pack pages can launch previews in the sequencer, so buyers hear how the sounds work together.
Connected to the catalog
The sequencer sits beside your hosted sounds instead of becoming another detached scratchpad.
Pack funnel
From preview to purchase without breaking context.
Grainstash keeps the creative tool and the selling surface connected. A visitor can try the pack, hear the loop, and return to the release page with the product still fresh.
