Ensoniq DP/4 Emulation Incoming!

[rafa1981]

That’s interesting, as it means Roland have recently updated their terms to specifically prevent this use.

The terms I agreed to when I downloaded it a while ago had no such stipulations, and as long as I don’t download it again, I don’t feel I’m bound by these new use terms.

But certainly interesting them updating their terms finally to be more explicit about allowed usage.

Ok, then my memory isn't failing. I tried to check on the internet archive but the only link to that page is from January 2026.

EDIT: This thread has a copy of the terms of some months ago. This must be where I did read it

And I assume you did read the terms before..

Indeed, many times and in detail, to see what use cases were not permitted, and I’ve discussed this here previously. The new language about the hardware the software runs on is there for pretty obvious reasons.

Thanks for making us aware of the new terms.

[rafa1981]

And I assume you did read the terms before.. I, like most people, I imagine, rarely read the entire EULA's in detail, just quick glance, agree and on with my business.

But indeed TUS now at least explicitly says for the owners of the original hardware...

I rescued the old terms from the boss site (a Roland company) by searching from the text on the KVR thread. Read above. Those are what I remember reading. Good to know my memory is not as disfunctional as I thought.

[zvenx]

Welcome.. Ftr, I never read the old terms in as much details as I did earlier today, I just expected Roland as normal to have a lot of legalese before downloading their stuff. (and I have been a Roland user since 1993 or so)

Sorry seems i'll pass.

[c_voltage]

Well ok, it's for 4U, but 1x algo are eat about 19%, that can't consider as ok too.
Or simple Signal Generator algo, with 17% cpu eating (?)

At positive side, i liked structure\the idea though.
Like implementing signal generator in chain, which can allow to make instant drone machine from this plug. As well some of reverbs algos are pretty good.

But seriously, if it weren't for the author's statement, I would have thought that AI was used quite intensively here, the optimization is so poor.
If this is ever fixed to consume x3 times less, I will buy it for 75 bucks or even more without doubts.

This is one reason poor DSP skills is not a good thing, it's one thing to solve for something, a completely different thing to solve for something elegantly and efficiently. I see many excellent products out there where it's totality obvious that if they were to gain the help of someone like Andrew Simper, the quality and efficiency of their stuff would go up significantly. I honestly don't believe you can do good DSP without a good knowledge of it.

[zerocrossing]

While I have personally called for this, I also think that if it can’t be done with reasonable resources, it isn’t worth it. The truth is, I’m awash with great multi effects plugins. Do I need those specific algorithms? No. Would I appreciate them if they were efficient at this price? Absolutely.

You guys are always complaining. You can render, you can freeze, but no...
Why don't you buy the real deal ? I have two units : 8 slots, approximatively 1800 euros on current market. If i use the 4 units operation, it means i can only process two signals at a time...

and...?

Sorry can't agree with this perception.
Even if a real device costs a million dollars and requires 50 cables to connect, that doesn't compensate for the absurdity of a simple tone generator consuming 17% of the CPU. (Or rather, that it consumes CPU at all.)
Additionally, i almost sure (based on many other great multi fx's which exists at market) that there is nothing in this routing shell that could require such calculations. (unless i did miss something special in features)

I had the real deal, but it was only useful on a send, as it was a major tone suck. I sold it when I moved from a hardware mixer to a software solution. It wasn’t worth the hassle, and I saw how many people were dealing with failing components, so I got out while the getting was good. It’s a nice flavor, but not necessary to make good sounding music. I don’t think it’s unreasonable to expect 34 year old digital technology to be able to be replicated on modern processors in an efficient way. I love to use effects in real time.

I looked up the TUS site, and it seems they have some old Boss rack and floor fx units in the works too. The Boss GT-5, caught my interest but, how good do those old digital algos still hold up to the plugin fx today, at the expense of non-optimized high CPU code? Unless you used one those units specifically for sounds and signal chain and recording back in the those days, I can't imagine that it would be useful to anyone else. Probably a wear once and throw away type nostalgia thing especially if its using heavy/50% CPU. The Boss GT floor multifx were cool to play around on in Guitar Center, I had some GAS for them, but ultimately if I was getting something like that I always looked to Zoom or something a lot cheaper that did the same stuff, and playing playing live in a band, you'd be hard pressed to hear the difference, unless it was a really unique creative effect.

Same here. I had one in my rack for about 3 months before I sold it. Never missed it after that.

Roland effects units were great. The R-880 and SDE-2000 were world-class. But yeah, GT-5, not so much.
