I updated to the new 2016 firmware. Now I only have presets in sampler but that’s it. No other synths have sounds!!! Please help me.
Wanna trade op-1s? Would love to be able to delete the presets 
Sorry can’t offer any help tho. Maybe mail TE if you’ve already tried factory reset and reinstall etc.
Have you tried shift + instrument slot (1-8). That’s the only way I have ever been able to access the presets.

Is there another way to get to them?
@MausB You are using Shift-1 under the screen, which allows you to ‘swap out’ the synth engine for the current preset (keeping env, fx, lfo the same) - and also lets you choose the sample waveform file which is why only they are listed.
As per @bc99 above, use Shift+1 (to 8) to select a preset for that slot.
Probably everyone who ever owned an OP-1 has done the same thing and said ‘where are the presets!’ 
Ah, thanks. That’s it. Welcome presets!!! Love the update btw. Cheers.
