Hey everyone! I designed a free op-1 field drum kit designer earthwire.space. There are a number of handy features: you can upload your own samples, easily access free sound libraries (like Freesound and Xeno-Canto), trim samples, change pitch and gain, change playback type, etc. You can also import kits you’ve already made and edit them in the tool. Please let me know if you like the site and if you have any upgrade suggestions or anything! Thanks
