Yes! Too many units flying around here. Don't talk about 3dB increase in loudness! dB calculations are only mathematically relevant to voltages and power. Power increase of P2 to P1: dB = 10 log (P2 / P1) Voltage (intensity) increase from V2 to V1: dB = 10 log (P2 / P1) = 10 log ((V2^2 /R ) / V1^2 / R) ) = 20 log (V2 / V1) Loudness: Empirically 2x Loudness = +10db Power = +20dB Voltage. So to your question: +20 dB power would be 2x ( 2x ) = 4x loudness To quote Ed McMahon, "You Are Correct, Sir". -

You are correct, up to a point. Yes, it sounded good. If you are a beginner and follow Joe's suggestions, your guitar will never play in tune up the neck. Never. That is not a good way to demonstrate one's expertise. It doesn't take long at all to explain the correct way to intonate an electric guitar, failing to do so sets up unexperienced musicians for failure. Not good. -

From a BTEE degreed engineer who knows audio engineering (me): A doubling of power is a +3dB change. Power is a dual unit system because it is the product of voltage and current. A doubling of singular unit such as voltage or audio volume is a +6dB change. dBu, dBV, dBm etc are all scales of dB systems with different reference points and unit scales. Reference points of 0dB is not the same voltage or volume between scales. However, changes of (x)dB that double the unit is consistent across the different scales. Yes, the dB system can be confusing. But before Bell Labs proposed the dB system, it was even more confusing. Another interesting fact: doubling the power of an amplifier results in only a 3dB increase in volume, while doubling the drivers results in a 6dB increase in volume. -

Yes, it's a thing. Statistically, 28% of all people have no sense of humor as well (38% in Nashville) according to psychologists. It's what causes threads to get deleted here every so often.

I just bought one used two days ago. I had in the past (a very past) the original ARP Odissey and an Avatar (the guitar version of the Odissey). They sounded quite differenti, and now I understand why: two different version of the filter. A friend of mine still have the all black one with coloured sliders, which Is again different, maybe two poles filter? Anyway the Behringer sounds good but a bit differenti too. My ARP had a ring modulator I used to build fabolous bell like sounds: metallic, full of harmonics. The kind of sound you can hear on Japan Tin Drum or Oil on Canvas albums. Until now I couldn't recreate this sound. Neither the Avatar did. Just my ARP Odissey I sold for little Money :( -
In V.A.S.T., be it the original V.A.S.T. or the newer vaster V.A.S.T. with Cascade and Dynamic, there are several ways you can use internal DSP sources with Samples: 1. Samples only 2. Internal DSP Oscillators only without any Sample 3. Samples mixed with internal DSP Oscillators In the new V.A.S.T., you can certainly use a multi-sampled Keymap, alongside an internal anti-aliased DSP Osc, e.g. a 2-block SINE+ for a single Layer, or even an aliased one like the old SAW+. For larger AA DSP Oscs, e.g. the 4-block SAW, you'd need to use Cascade Mode, a passthrough signal and a Mixer ALG. So these aren't mutually exclusive. Instead, what the manual seems to indicate is that if you want to do a traditional analogue subtractive synth, then you'd rather not use a Keymap, which makes sense since analogue subtractive synths don't use them at all. You can still use a Keymap's sample Envelope if it is set to Natural, even if the Sample itself isn't sounding via the Layer, say, if you have simply a 4-block AA DSP SAW. That SAW block effectively cuts off any of the Sample signal. However, as the AMPENV mode is set to Natural, it is the factory AMPENV for that multi-Sampled Keymap that is applied to the Layer. The Natural envelopes have more details than can be produced with a User AMPENV. The thing that happens with setting the Keymap to Silence is that it sets each key's amplitude to the same maximum amplitude. Maybe that's what you need in a certain program, but sometimes, if you are doing an emulative program, you could be better off actually referencing the emulation's Keymaps Sample although the latter isn't heard, with the corresponding Natural Envelope, or of course, you could just go into User Mode and make your own envelope. Hope this helps. -
Sweetwater might accept to deliver to Canada, but you will be charged transport accordingly and as anything going USA to Canada your item will go through customs and it is always possible to end up with extra fees - sometimes very expensive. I personally had a very bad experience about 10 years ago and promised myself to never import again from the USA unless the seller confirms on paper he pays for all possible customs and duties extra fees. Buying Kurzweil products in Canada has always been complicated. In the 1990s a few stores in the province kept a couple of them, but if you wanted something they didn't have you had to order sight unseen and wait months to get your purchase. That is how I bought my MIDIboard, K1200 and finally, around 2000, a PC2X. I hated the Fatar action on the PC2X from day one and swore to never buy a keyboard sight unseen ever again.
