    Also, does random source just mean the way a S&H wave plays randomly?


    AFAIK, Sample & Hold in general takes an input signal, periodically (at LFO frequency) measures (samples) this input signal and outputs the measured level for the whole period. If you feed the S&H a periodic signal, the output will be somewhat predictable and periodic as well. If you feed a random signal, like noise, the output will be a series of random levels.

    OK. My memory was less good than I thought.

    You find a great collection of "well-know" sounds for covers in the "Classic Live Patches for Virus TI" bank which can be downloaded.

    BTW, Rick Wright often played Grand Piano, E-Pianos, Clavinets and Organs (not necessarily a Hammond) and Mellotron with a little bit of effects processing. So those basic sounds may be a good starting point.

    Which PF songs do you want to play?

    There are a couple of PF sound emulations in the ROM banks. They are named accordingly. Search for "floyd" and words from song titles, like "were".

    IMHO there hasn't happened anything new in the domain of digital synths since 2009 in general. The Virus TI and the Blofeld are still the top hardware synths.

    And on the workstation side of things, we're still limited to a couple of GB sampling memory while computers run off SSDs with TBs of space. The best offering is a 60GB SSD on the Kronos, all other hardware (synths, workstations, beatboxes, sample toys) are good if they offer 128MB (Kurzweil) or a whopping 2GB SD card (Akai) as storage. And don't get me started on the topic of hardware samplers... technologically the whole music industry is stuck in the late 90's to early 2000's. And most of the new products are ridiculous unprofessional gadgets.

    I for one prefer Access to keep producing a single dated model of a professional top synth instead of replacing that with ten useless dumbed down but dead cheap toys.

    However, I'd also love to see a TI3 with 10x the CPU power and a couple of features from competitors (Comb filter, step sequencer). :)

    Regarding Initial Phase: Play around with the two OSC with identical settings and change the Init Phase value. I think it will become immediately obvious. Now if you think about doing the same with 8 voices you'll probably also come to the conclusion that two start different sets of initial phases might never produce the same spectrum regardless of how long you wait. Naturally, my logic may be flawed...

    However, by now I'd really like to hear/see an example of the OPs "problem", because I don't have the means to do exact spectrum analysis, and I'd really like to know whether I simply don't hear the difference.

    The Virus Control Center application and the Virus Control plugin do different things. Both are installed by the Access Virus TI Software installer which can be downloaded from the Access website.

    Generally speaking:
    - The VCC application is used to maintain your Virus, like making backups of the complete synth, burning preset banks to ROM and updating the firmware
    - The VC Plugin is an Editor and Librarian for the Virus TI and is used from within your DAW to integrate the Virus hardware synth as if it was a AU/VST plugin synth. VC is also great to create or tweak presets and to manage preset banks.

    For further information, please consult the documentation which is also available online.

    Just tried that with my Darkstar TI2: It's also on "auto" and always goes into "synced to host" when USB and connection to DAW is established regardless of whether the Synth or the Mac is switched on first.

    Thank you for giving this issue some thoughts!

    I could be wrong, But is the issue your facing just distortion?

    I don't think so, at least not in a typical "audio distortion" way. If it happens, certain notes will sound like whole chip tune melodies before settling on the final (correct) note. And it also happened on very simple patches while I was exploring FM without any effects on. But you could be right with your assumption that the added amplitudes produce some sort of overflow which lead to completely wrong results for the calculated waveform.

    I just tried that myself and come to the following conclusion: Unison detune introduces some randomness in a way that if you hit a key ten times in a row, each note will sound slightly different. If you keep hitting the same note with Unison 8 detune 58 you'll hear that sometimes it will sound considerably thinner and sometimes darker. This is due to the initial phase of the voices. If you set Phase Init to a fixed value, every note sounds the same, also if blending between OSC 1 and 2. And there is no difference at all if Unison is off. At least not one I can see or hear.

    psylence: what spectrum analyzer did you use? Looks nice!
