DESCRIPTION: the spectraloscils effect is using Victor Lazzarini's pvsadsyn. It resynthesizes using a fast oscillator-bank. Using the Increment knob, together with other setting, might result in an error. There is no protection for it (yet) but it does not blow up the computer either... --- version 1.1, September 2021 - now i rate knob are re-initialized version 1.0, September 2021 - initial version by Menno Knevel

a wrapper of ladspa plugin 4262 called AutoTalent, created by Tom Baran. All of the code but the FFT routines is licensed under GPL2. plugin has mono input, mono output. See: http://tombaran.info/autotalent.html The dssi opcodes are wrapping the ladspa plugin so it can be used as an effect for Blue. The PATH for the ladspa plugins on my Linux systemm is /usr/lib/ladspa. Be sure to set the right PATH if you run OSX or Windows. DESCRIPTION: It's a real-time pitch correction plugin. You specify the notes that a singer is allowed to hit, and Autotalent makes sure that they do. You can also use Autotalent for more exotic effects, like the Cher / T-Pain effect, making your voice sound like a chiptune, adding artificial vibrato, or messing with your formants. Autotalent can also be used as a harmonizer that knows how to sing in the scale with you. Or, you can use Autotalent to change the scale of a melody between major and minor or to change the musical mode. CONTROLLERS: ON/OFF - bypass File Selector - set path for autotalent.so Concert A - value in Hz, the basis for the whole effect Fixed pitch - pitch (semitones) toward which pitch is pulled Pull to Fixed Pitch - degree to which pitch is pulled toward FIXED PITCH. 0 = use original pitch, 1: use FIXED PITCH A/Bb/C...Ab - notes in scale correction strength - strength of pitch correction correction smoothness - 0: abrupt transitions, 1: smooth transitions Pitch shift - # of notes by which output is shifted Outout Scale Rotate - # of notes by which the output scale is rotated (change scales) LFO depth/rate - gain and frequncy of LFO LFO square/sine/tri - 3 different LFO waveforms LFO symmetry - rise/fall of LFO wave LFO quantization - just that Formant Correction - 0: no, 1: yes for shifting formants Formant warp - change color of sound mix - mix direct signal with effect --- version 1.02, July 2020 - added BSB information comments version 1.01, May 2020 - added comments on controllers version 1.0, June 2019 - initial version by Menno Knevel

DESCRIPTION: Harmonizer, based upon the code from the Csound Book p.466, instr. 2209 - This is a stereo version. - switch between 12 tone division or free CONTROLLERS: ON/OFF - bypass delay time - delay time needed for analysis of incoming signal. feedback - feedback of input signal LFO - LFO using a sine wave switch - choose between free pitch or 12-tone mode pitch - free adjustable pitch semitone - 12-tones in an octave mix - mix direct signal with effect --- version 1.02, July 2020 - added BSB information comments version 1.01, May 2020 - added comments on controllers version 1, february 2019 - initial version by Menno Knevel

DESCRIPTION: stereo harmonizer, based on harmon4, with up to 2 x voices. Can be mixed with direct signal. CONTROLLERS: ON/OFF - bypass update - pitch analyze update: length of period, in seconds, that outputs are updated treshold - amplitude, expressed in decibels, necessary for the pitch to be detected detection low/high - range in which pitch is detected frequency 1/2/3/4 - the 1st, 2nd, 3th, 4th generated frequency mix - mix direct signal with effect --- version 1.02, July 2020 - added BSB information comments version 1.01, May 2020 - added comments on controllers version 1.0, 2019 - initial version by Menno Knevel

DESCRIPTION: The VoxXtended has 2 methods to vocode the incoming sound. 'method Q' uses 4th order butteworth filters and 'method pvs' uses the pvsvoc opcode, both with a distintive sound. CONTROLLERS: ON/OFF - bypass Dropdown List - switch between Method 1:Q or Method 2:pvs. 2 totally different approaches to vocoding the incoming signal METHOD 1:Q (traditional vocoding) freq limits - sets boundaries to frequencies of the filters Q - Quality of filters bands - # of bands volume - gain of effect swap source - switch between IR or incoming signal METHOD 2:pvs depth - depth of effect, affecting how much of the frequencies will be taken from the second signal gain - gain boost/attenuation applied to the output coefs - number of cepstrum coefs used in spectral envelope estimation overlap - The distance in samples (?hop size?) between overlapping analysis frames size - The FFT size in samples swap source - switch between IR or incoming signal EXCITER or modulator SIGNAL fine/coarse frequency - fine and coarse tuning of modulator frequency Dropdown List - 5 different waveforms for modulator, where the 5th is the Sample File Selector - choose Sample to modulate/excite incoming signal start sample - skip in Sample loop start/end - set start and end loop points pitch - set pitch of Sample --- version 1.12, July 2020 - added BSB information comments version 1.11, May 2020 - added comments on controllers version 1.1, february 2019 - now works without a soundfile - some GUI clearing up - all stereo now version 1.0, january 2018 - initial version by Menno Knevel - uses same exciter signal block for the 2 methods - a soundfile must be loaded - method Q uses UDO from Victor Lazzarini - when using a soundfile as exciter, option to change loop start and end while playing
