I recently got it and the flexi sampler is pretty much the same as the OT, the modulations are different because Drambo is basically modular & the sampler is a module, so you can assign as much modulation for parameters as you want.
I had an OT for years & loved modulating start position & also used sample chains a lot. It doesn’t load sample chain presets directly but the transient detection is really good & so it doesn’t really matter, just load the WAV & you can split via transient or equally.
Here’s an example of using an LFO to modulate sample start offset, it pretty much feels identical to using the OT. Sorry it isn’t a great video but hopefully shows the concept in action.
In terms of Sequencing, it also feels very Elektron, it supports clicking a step and holding notes on an external midi controller just like the Elektrons (which is something I really like) & also has conditionals. The conditionals are well implemented as sliders which decide the cycle range, however instead of choosing a single positive/play step you can select multiple so you could have it play 1st and 3rd every 5 beats for example. That’s a nice extension to the idea:
It also supports P-locking via hold step and move knob.
I haven’t spent too much time with it yet, but I think it’s seriously good for people who like working the Elektron way & it also works on a Mac (although normal AU’s aren’t available for tracks), it even loads into Logic as a plug-in.
Where it isn’t like the OT is that the instruments are for the entire project as opposed to distinct ‘parts’ so that’s a significant area where they diverge.
Somebody has actually built an OT instrument clone built with the modular components that you can load on a single track, and even an entire 8 channel instrument for a single track, although I prefer just building stuff as I work so far. The single channel instrument is great though & demonstrates what can be done with the modular side of Drambo.
Sorry for the long post!
