Randy, somehow i can't find the actual e-mail containing the final beta installer, just the sounds and palettes e-mail made it to my box. Would you mind re-sending it to peterjacksonitis AT gmail.com ?


that's great, i wasn't envisioning doing anything too fancy with midi control over those but it would be cool to be able to have a slow sequence changing those parameters tempo synced to a regular note pattern. But it would also probably be really weird (but nice) To let you modulate those choices internally apart from midi too.

one request for the final version: sample changing / model type / body all midi controllable. On Live I am unable to access those with a midi controller, but maybe it's just a Live thing, does it work in other hosts?
this plugin is amazing Randy, thanks for all your hard work

edit: trying to CV 2 midi kaivo externally (using an analogue solutions eurorack module) and its choking quite a bit, i think any really fast midi control seems to spike the CPU.
right now I'm trying 4 ccs at the same time along with midi note pitch and none on/off.

good to know, thanks Randy. I'll play around with it some more tonight and experiment with multiple instances and trying to be conservative with the cpu for each one. Would you say those factors you mentioned or less /equally/more important than the voice amount itself in terms of cpu usage?

"Over here it's been so far so good. I've managed to run multiple instances of Kaivo with everything turned on & 3-4 voice polyphony and it's not done anything odd."

just curious what system are you running? I tried running only 2 on a 2.8ghz intel core i7 macbook and i could barely get them to go smoothly. I haven't investigated deeply enough to know if different modes or models or actions take up more cpu or not, but so far it only seems to be the voice amount.

Randy, just wanted to throw this out there. Have you played with the Logic Audio plugin Sculpture? I ask because of all the physical modeling synths I've used (and I've used them all.. hardware included: vl1, vl70, technics wsa1, korg wavedrum) Kaivo has most similarities with Sculpture. I'm only comparing the timbre characteristics and tweakability of them both. They share a similar lineage. Since Sculpture is exclusive to Logic I'm sure it's not going to offer more competition, but I'd suggest checking it out to see what overlap there is and what things can be implemented into Kaivo to differentiate it and make it ultimately a much more usable instrument. So far Sculpture is a lot less controllable and is a harder beast to tame. My 'test' for doing this was setting up a random CC array to change each knob to a random position, and with Sculpture you get usable results about 1 out of every 5 'random' bursts, with Kaivo I'm getting good results about 1 out of every 2. Sculpture divides things up differently, to be able to use audio clips to control the models it has to be loaded as an effect, where yours does not and that is already a huge advantage. Quite easily though I'm sure you could also turn yours into some kind of insert effect.

Sculptures strengths are percussion, plucked strings and rolling/jittering sounds. Right now Kaivo has the same strengths and I'd argue it's stronger as it already stands for these types of sounds, but what they both lack is the ability to do convincing wind brass and bowed string sounds, and i think if you could really dial these types of sounds in before the final release you will have a totally unstoppable beast with no comparison in the software realm.
edit: and I know you're already working out the CPU hogging nature of Kaivo, but Sculpture on my same system can be run in about 5-6 instances, sometimes even up to 10 without maxing out my cpu.

One suggestion for the limiter, it would be nice to not just have a built in limiter but also a compressor. For both of them though something visualizing the gain reduction taking place would be helpful, so you know how much it's going over the zero so to speak. A plugin called Pianoteq has a built in limiter and is a good example of what im talking about in terms of visualizing the gain reduction.

  • yes on more bodies
  • and more models like 'pipes'
  • some kind of brown noise or s&h random stepper oscillator/generator would be helpful on top of the controller sources already here, so you can have something like a random decay/sustain time for every time the note is plucked or struck
  • some kind of feedback loop mode where you can route the end of the chain back into itself at the beginning, for physical modeling this might be tricky since it's so unpredictable and 'spikey' already but Kaivo is probably one of the smoothest, if not the smoothest physical modeling synths i've used with this much tweakability.

the only thing i haven't been able to create effectively that i like doing in physical modeling is flute and horn type sounds, but maybe i'm missing a technique or trick on how to achieve this.

Wow Randy, this synth is absolutely amazing. I can't get over how awesome it is to control physical models with samples like water and human voices. I spent about (no joke) 12 hours fiddling with it into the early morning hours and I still haven't scratched the surface. Just posted 3 new demos of Kaivo in the soundcloud group
