Les sons sont pas mals mais je ne trouve pas qu ils soient très accoustiques dommage ar j avais vraiment besoin de sons de piano et autre mais la qualité du pack est là donc je ne retire qu une étoile pour cela

Nice pack for some CT diversity.
I thought I'd try out this pack as I'm new to circuit tracks. I got the tracks on offer, and mainly wanted something self contained and portable. I'm an oldy, I used to record and produce back in the day when tape was actual tape (2 inch) and you WALKED from one end of a console to the other :)
Anyway... I'm more trying to fuse the tracks with something rock oriented, and yes, would you believe, Irish trad, so I'm not so into the more grungy "nasty" very electronic sounds the tracks tends to produce.
Some might say the CT is not for this, well challenge accepted.
I appreciate the demo videos and the shopping experience with isotonik studios is smooth as can be.
Not all of this pack is of use to me, but well.. I believe isotonik is based in the UK? I haven't been there for a while, but I think I paid like the price of a pint in a fancy bar for this, so you can't really go wrong. :-)
Thanks!
Some great clues for how to use the tracks synth engine to make a range of sounds. I still need to investigate more what I can do with these patches. I like some of the bass, really nice.
Personally, the chord stabs and crackle and that are not much use, that stuff abounds so I feel like it starts to feel tired very quickly. and I'd rather just play my own chords if I wanted that. That said, some of the subtle usage of the samples in the demos projects is nice. Not that this style is something I would actually listen to as music, you know, so take my opinion with a pinch of salt.

This is the first pack I've purchased for Circuit Tracks, because I specifically wanted some more organic instrument sounds. I'm very happy with this pack and I'm already putting the bass sounds to work on new projects. Thank you!

One of my go tos for sure when I work my way to this machine. I make a bit of lo-fi and ambient electronics. The keys okay an integral part of what I do and this fits the bill 100. Thank you so much for the time and work you out into these. Keep this coming. Would love an evolving generative pack. Morphing everything. Airy spaciousness. Plucks. Just real evolving movement

Ever wanted a real sounding piano Patch on the Circuit tracks? Or maybe an acoustic guitar bass, that could pluck more if you hit it harder, and yet retain its low end autheticity. Keys brings an end to this search allowing you create realistic sounding acoustic music such as rnb and soul and a lot more. no more trying to work out a way to get a piano in your sample pool.
Using old synthesis techniques such as La Synthnesis, Freqency modulation, and slight wavetable manipulation, it is possible to create the slight nuances that make things resonate in an authentic way and play naturally on a keyboard or circuit. Keys does this in order to bring you traditional sounding acoustic instruments.
Featuring a huge amount of authentic sounding instruments in the patches and crackle samples, aswell as chord samples. This pack makes it very easy to create your own version of an nostalgic track in any genre and add that flavour to sound.
With over 16 sessions boasting 9 different genres, Keys leaves no stone unturned transforming the circuit tracks in to something beyond what it was intented for. you will find many new techniques in the sessions such as shifting steps, swing, a new scale probability trick if you can find it!?!?
Velocity sensitivity is key here, please make sure to turn it on.
You will find that if you play softly on bass guitar, it is more subby, but if you play hard or programme in loud notes you will here the twang. similarly on all live instruments, velocity plays a big part.
