So, we’ve been experimenting with a new delay architecture for a long time – c.f. EuroDDL and DDL-500 – and this is the next step in that evolution. We took the same high-resolution digital delay line, wrapped it in analog filters, feedback and dry/wet mix. The key, though, is that we added an analog modulator that directly modulates the converter sample rate over a wide range. With this, it turns into a modulated delay in the style of a bucket brigade, albeit at a very high sample rate and resolution.
We took that concept, opened it up to allow some crazy extremes, added some presets, and added a glowy Rose in the middle.

So, in addition to getting up to 50 sec of delay, it can go to sub-millisecond delays (so you can get some really cool flanging and comb filtering sounds). The mod rate won’t get quite up into audio rate, but it does go from glacially slow to really choppy and fast. The mod depth goes really deep (it will shift up to an octave).
It also has analog feedback that will go a good notch above unity, and a resonant filter. These, in combination with the modulation, let you get some really cool self-oscillation and ringing.
Finally, the expression pedal can control everything, and the hotswitch has tons of flexible options (including infinite repeat and the ability to quick-switch between sounds), which (IMO) turn the Rose into a really cool performance/improvisation box.

Tell us about the delay time available
Since the sample rate is directly modulated, the maximum delay time is related to the sample rate. At the highest sample rate, you have 10 seconds of delay time. At the lowest sample rate, you can get 50 seconds of delay time.
Is there an actual DIN port for MIDI?
No DIN MIDI, only USB MIDI and TRS MIDI through the expression pedal jack.
What is the USB port for?
Updates, MIDI control, preset swapping, and some things we probably haven’t thought of yet, but might do in the future.
What are the modulation wave shapes?
There’s a modified sine, square wave, random walk, and an envelope follower. You can also directly modulate the delay line using a knob or the expression pedal.
