nb: I changed your topic title since “Kick 1 help” was very generic & confusing `
Unfortunately, Kick 1 is no longer available for sales. Why is that ?? : because though Kick 1 was already a great plugin ( as you’ve been able to test already ) Kick 2 is really a dramatic upgrade, fulfilled with enhancements & new features making it probably the best soft-synth kick designer tool on the market, thus making Kick 1 outdated.
I suggest you to try the Kick 2 demo available on the product page KICK 2 | Sounds and to watch the videos to give you an idea of what Kick 2 is capable of comparing to the first version.
Alternatively, the only way you could get a Kick 1 licence is by buying it or getting it from your friend or someone else, there is a transfer licence procedure to follow between the seller & Sonic Academy, but again, Kick 2 is really what you should fall in love with after taking the time to dive into the demo.
