They say practice makes perfect and so as you continue your journey with this you will certainly gain more confidence and become more instructional with this work. I to listened to the end and found it very relaxing and personal as well as did learn a bit about some older Roland equipment that I didn't know. I have a Casio keyboard which at the time it was purchased (1998) was the best unit they had out at the time. My wife got it for me for a Christmas gift. I too work on a budget, which is a retirement budget, but have everything I need, for the various music I create. I enjoy making my own samples and loops and incorporating them into some of my work. As for guitar the best purchase I ever made was a Digitech GNX4 processor, which allows me to set up my Yamaha mixer, guitars, microphones, keyboards, monitors and amplifiers all thru the single unit. From what I could see in the background of your video, it look as though you have guite a setup going in your room there. Enjoyed meeting the dogs and wish you well with your musical/video adventure.
Peace and Blessings, John
