Yes, that's a known entity, and not just limited to that sound.

It's due to Legato being used on a sample-based waveform. Unsure if you know about the waveform structure of ROMplers, but for each sound (Program) there are multiple different samples key-mapped across the spread of the entire keyboard, in different zones. This is so that several samples can be used discreetly for a more natural representation, rather than just pitching up or down just a single sample across the entire range, creating chip-munking or aliasing effects.

In theory with legato, what should happen is that the original key being pressed will be pitch-bent upwards, in a slide, when you hit the next note, similar to portamento in analogue synthesis.

However when you're using a ROMpler - a sample based engine - the original sample played can only be pitch-bent so high until it reaches the limit for processing that particular sample and/or in that key-map zone.

My best advice is to only use sounds with Legato with notes in a localised area to the key you are pressing, rather than several octaves up from it.

Alternatively, if you don't want the Legato pitch-slide effect, you can always turn it off so it will trigger new samples (in their respective keyzones) each time you hit a new key, and you will be able to play any notes and they will be pitched normally. To do this, hit Program, then Edit, P1, then ProgBasic tab, then untick the Legato setting.

I believe the Legato bug also affects the Triton. I think it's a consequence of digital processing with limited DSP in those eras. The Trinity was released in 1995, a ground-breaking leap in its time, however it's expected there would be a couple of chinks in its armour when compared to modern hardware, and that is one of them.

It only applies to the Trinity sample engine. If you have Moss, which doesn't use samples but uses mathematics to generate its oscillators, you can use Portamento at will.

Please re-read my post above.

It's a known bug, related to the Legato setting when using samples that pitch too far into other keyzones or reach the limits of pitching for that sample (the note you are holding).

The notes you are playing at the top are not new triggering new samples, you're instead pitching the low noted sample upwards. But after being stretched up 2 octaves or so, it's being stretched beyond its limit.

Either stick to only playing notes +/- 1 octave of the note pressed, or turn Legato off.
