Yeah but then it would sell less. You've got to suck people in with a sleek but simple UI, then pulverise them when they look at the under the hood. It's important to leave people a speechless as possible, that way you have less questions to answer in the forums.Funkybot's Evil Twin wrote:If The Scream looked more like The Drop, without the input/output cables and empty space and lots of big knobs, I think it'd be a lot more functional.

The best one currently is (IMHO) a Reaper/JSFX plugin called Skope II by Sonic Anomaly (http://sonic.supermaailma.net/plugins). It can do almost all the stuff you mentioned, plus it can accurately sync to the loop points set in the daw, even with very short times, and it can display several signals overlaid on top of each other.andy-cytomic wrote:There seem to be plenty of FFTs, but not many good scopes, and even fewer that are good at both - if anyone knows of a really good scope then please let me know as this will save me time! I want something with the functionality of a regular oscilloscope eg the picoscope software here: https://www.picotech.com/oscilloscope/5 ... e-software (it doesn't have to be this advanced, but just something with adjustable triggering, zoomable display, horizontal and vertical markers that can tell me the delta between each, and some waveform stats eg average dc level, rms, max, min etc.)
It's not the UI mess I'm worried about, it would increase the CPU by quite a bit. The number of diodes is approximated by scaling the the "_n" and "_nr" numbers in a single diode model, so you can get close behaviour to any number of diodes by changing one number at no additional CPU.contrast wrote:If I was gonna pick nits (so clearly I'm gonna) about the functionality I'd say it might be nice to be able to choose multiple diode types in addition to the quantity for each of the two diode chains, but that's probably a UI/etc hassle. Fantastic as is though!
What is on offer is a slightly modified Boyle macro modelled BJT input opamp, which, from what I can tell, is already more than any other plugin I've tried does! Sure you may be able to "pick" different opamps, but they aren't actually modelling much, and from what I can tell no model of the TS808 I have tried models the differential pair BJTs (Bi-Polar Junction Transistor) at the input stage, including finite beta - which is pretty critical to the sound and very easy to spot if it's not done! If you head to the FULL mod section and configure it to match the input stage and basic parameters of any BJT input opamp you want, but only if the opamp isn't doing anything weird. That's all that will be provided for The Scream.Ivan_C wrote:Quick question : would it be possible to change the opamps model as well ?
I don't know if it's true that in the analog world, picking different opamps can have such a huge impact on the sound as described, but indeed there are a few opamp parameters to tweak in "The Scream", so that offers already an equivalentThere seems to be a difference in sound depending on what opamp is actually in the circuit. In fact, this may be the single biggest effect on the sound of the TS circuit. The JRC parts were undoubtedly chosen by the design engineer primarily because they were cheap. During the time the 808 was in production, the JRC was oneof the cheapest dual opamps on the market with acceptable audio performance. As such, it was used in huge volumes of Japanese audio equipment. The opamp is described in some Japan Radio Corporation (JRC...) literature as "an improved dual 741 type opamp with better noise, drive capability, and slew rate than the original 741 type opamps". Note that this is not saying much, as the 741 is a fairly abysmal audio part.
For some reason, the JRC4558's seem to be well suited to duty in the TS type circuit. JRC later changed its name to New Japan Radio Corporation and made parts titled "NJM4558". When you order these, you get parts that are labeled "JRC4558". By all reports, these sound as good as the original. The tube screamers made with 72558A are reported to sound abysmal. From the brave souls who took the suggestions in the tube screamer clone section over on GEO and put in a socket to swap parts, the following types of opamps DO seem to sound good.
- new manufacture JRC4558D
- LM833
- RC4558, made by a couple of US firms
- TLC2202
- TLC2272
- OP275
- LT1214
Yes, the opamps will make a difference, but the 4558 is largely agreed to be the best sounding one for the TS series (and is used in the SD-1 as well). The LM833 is a very similar circuit to the 4558, just a bit brighter sounding and slightly cleaner sounding. The OP275 and LT1214, from the datasheets, will be cleaner again, but I won't know about those till I have them on the bench and test them out. The TLC2202 (edit: and TLC2272) is a radically different opamp, it's mofset based and I'm guessing those models aren't popular, so if we skip on those, then all the others have BJT PNP differential inputs so we'll be able to get some basic modelling of those done via the existing parameters!Ivan_C wrote:Oh ! I didn't realized that the FULL mod page had a few parameters allowing to tweak the main opamp behaviour.
What I meant is that it would have been great to be able to pick in the first mod page different opamps, such as the ones described there : http://www.geofex.com/article_folders/t ... sxtech.htm
They say there that :

And thanks for all the information !
Thanks! I'll spend some time getting the Win 7 people up and running, and fixing another few small bugs first since that will be needed for The Glue update as wellHcDoom wrote:Sounds great...amazing sound quality! Great job, Andy!!!

. Andy, since you've explored this MOD thing, maybe it is possible to include modding into the updated version of The Glue as well? There are various "inspired by SSL" units (from Dramastic, TK Audio etc) which use different amplifier topologies, transformer outputs etc, so maybe something along the lines could be implemented?I believe that would be too complicated...imo, its better that Andy updates Glue with one proper SSL unit and emulates all nonlinearities, thd, etc etc. I would also like to keep clean version (as it is now) and new analog, colored version...so we can switch between those two modes. Since The Glue is definitely best vst compressor for me there is...any update Andy comes with will be great as he always delivers top notch high quality products.meloco_go wrote:I gonna keep waitingandy-cytomic wrote:Thanks!
