There is a second cabinet on the top : ruclips.net/video/32XRAH3-PWs/видео.html

@@lnefpd Yes I see that now. The 104 is the best filter I have used. Nice having a bank of them to work with. Are you planning to use any of the AMSynth modules? Thanks

Thank you !

Actually you cannot do this with the 914, because it is not resonant. But you're right : i found the sound not very convincing, compared to what you get with a filter bank made with several Behringer 1047s.

914 also uses cheap ICs. it is original Moog 914 that uses big inductor coils, and that is an insanely beautiful sound. unfortunately, there is no shortcut to make it cheaper so Behringer didn't bother. altough these two are different things really. 914 is a fixed filter bank. Spectravox is a ffb, a spectral processor and a vocoder. you need ton more circuitry per each band - a detection filter, env follower, vca and a filter for the carrier, plus cv control. that said, i agree, Spectravox ain't exactly the best sounding. fwiw, i prefer the sound of Sputnik SP and TTA 296t .

For the melodic / whale voice : the VCO is the one on the middle (of the group of five side to side). The pitch is controlled by : - a (1036) S&H (black cable on FM 1 input), attenuated so that it covers a range of about two octaves, - a triangle LFO (orange cable on FM 2 input), strongly attenuated, so that it moves the pitch by only a few semitones. I'm trying something similar, with a sine instead of the triangle LFO, in the upcoming « n°160 » (i'm editing it right now). For the inharmonic voice : it's a combination of two VCOs. The first one goes to the input of a 1047 filter. The second one goes through a 1005 VCA and then to the FM input of the filter. There are three random modulations (from S&Hs) : the pitches of the two VCOs (with no attenuation, and the frequencies of the VCOs set quite low so that, with a negative voltage from the S&H, it can reach the LFO range), and the third random modulation is for the VCA (thus controlling the amount of FM on the filter). A LFO is modulating slowly the resonance level of the filter. And for better results, you may duplicate the different input signals and send them to several 1047 filters, with increasing cutoff frequencies : the first one will be a LP, and the others BPs. Which makes a little filter bank (here i'm using just two). I've experimented with several combinations of wave shapes for the two VCOs (see for instance n°153, n°154 and n°155).

@@lnefpd Can't wait to try this out! Thanks.

Haha yes… while inside their birds of prey… 👌💯
