I am actually not fond of the VU being locked at 600ms now. I understand where you try to aim at (loudness measurement, since this device can be used as exciter). But please offer a switch or multi-rotary switch for 300ms unweighted/400ms k-weighted/600ms unweighted. Personally I still use 300ms unweighted for MOST plugins, including XTC. I'm just used to the ANSI C16.5-1942/British Standard BS 6840/IEC 60268-17 standard for VU's while using such plugin on individual channels. Mastering is a different topic.
Then the addenum of the manual:
This confuses me a bit. Either the +9dBFS is a type and must mean -9dBFS digital peak, or the control of the plugin is actually turned around.DRIVE adjusts the internal gain for the stateful saturation circuit. BOOST adjusts the level of solid 2nd and 3rd order harmonics as well as the internal headroom. The 0dB setting is calibrated to have a headroom at around +9dBFS upfront clipping occurs. The device can be driven even hotter in 3dB steps down to a headrom at around -3dBFS.
To my understanding, the plugin is now internally locked to -18dBFS (RMS) if the BOOST mode is setup to 0dB. The +12dB boost would result in -3dBFS as reference level which would result in a +6dBFS signal (32bit float) as ceiling prior to clipping (while still offering +9dB of peak headroom, or better said "dynamic range").
Question:
Is the clipping like "digital" clipping (read: destroyed signal), or does analog type clipping occour?
And... a question on the modes:
I think Contemporary is the old saturation design of Tessla Pro, right? The US console should be an SSL typish sound, the British should be (well) NEVE. Tape and Tube is pretty much self explanory.
I see five additional reserved slots - what are the plans for that? Only if you know of course.
Else, love the update already (except for the VU maybe).
Now I can use TESSLA PRO as "poor man's console". Well, it was possible before, but not without drastically messing with input/output gain. Though it doesn't offer any crosstalk like most other summing devices. But heck, for this there are suitable known alternatives.
Thanks for the efforts.
Definitely looking forward to BootEQ mkIII with a reference level mode. 3dB steps are fine with me. Though I already hear people asking for "why not label it -18dBFS up to xy" or "why is there no reference level for -24dBFS or -20dBFS?", etc...
loved what you did with the console's!!!
I've worked and studied hard over the past few years to get ITB mixes that sound alive, wide, deep and warm, using several plugins (lots of yours) including some of latest console and tape plugins that have been recently released and I've been very pleased with the results. But Tessla Pro II is just unbelievable. This one has me scratching my head wondering if I have wasted my money. Another classic my fried. Wow!
