This keyboard has two basic bends, both dealing with the sustain of the note played. One knob will shorten the amount of time a note will play, while the other will lengthen it, and both can also pitch the tone down. These two bends can be mixed to very interesting results. I have added a 1/4" out out jack, and it takes 4 AA batteries.
This, in my opinion, is a pretty nice little synth. The guts of it were so simple, it was easy to get a lot of functionality out of it. The bends installed cause it to play an ever present tone, which can be distorted with the red and gray knobs. You can blend this tone with a tone generated by a key press. This will cause some interesting sounds, as the tones are mixed. You can flip on the switch above the red knob, which will play a specific not from the keyboard, so you don't have to hold one down, while exploring the possibilities. The center green knob has two switches associated with it. If they are both in the "off" position (down) the knob will do nothing. Flip the left one, and the knob will control distortion, pitch, beats, etc, or flip the right one, and get different results, You can even have them both on simultaneously for more options. Really, there are too many possibilities with this instrument to show in a 5 minute video, but I did my best. You'll need to obtain this, and try it for yourself. I installed all my controls where the battery back would nestle, and thus had to cut it out. I installed a new external battery pack, and it is attached to the front of the instrument with velcro. It takes 4 AA batteries. It also has a 1/4" output jack.
This keyboard has two simple bends, controlled with a switch and knob. They are both pitch bends, and both pitch it down. When the switch is in the up position you get a pretty normal pitch bend, using the knob to take it down pretty low. When the switch is in the down position, the knob will take the town from pretty low, and disintegrate it into patterned clicks, and sometimes interesting "beats". It's a pretty cool instrument. It takes 4 AA batteries. It also has a 1/4" output jack.
Here is a little speak and spell clone that you see everywhere. It's ability to teach a kid to read, I question, but it is good for making noise. I installed a pretty simple pitch bend in this one. You can pitch it down with the knob, until the voices and melodies pretty much disintegrate, or pitch it up to get interesting distorted effects. It makes a pretty cool sort of drum machine, as I found out. It takes 2 AA batteries. It also has a 1/4" output jack.
This is an interesting keyboard. I could not find most of the normal bends you find in the sort's of toys, but I did find a good pitch bend (down). The interesting thing though is the loop bends I found. There are two, but potentiometer controlled, and switch activated. They will sustain the tone played indefinitely, but, this little keyboard has a two tone polyphony, thus when the one of the loop bends are enacted, you can combine two tones. This get's really cool when you turn on the vibrato, and pitch the thing down. It acts a little different when amplified, so I've included what it sounds like playing from the internal speaker as well. There wasn't much room in this, but I did the best I could. I have included pictures of what the best I could do looks like (added character). Takes 6 AA batteries.
I like this thing. It's a toddlers keyboard and animal sound maker. It had a very good pitch bend that takes the sounds, and completely destroys them. The disintegrate into peeps, and sequels, and rhythmic patterns, and drones. I'm sure you'll find it very wonderful. Usually I am opposed to removing any of the original functionality of a toy, just cause I'm a little eccentric, but there simply was no room inside this to install parts, so I removed the speaker. Along with the pitch knob, I also installed a 1/4" output jack. Takes 3 AA batteries.
This is a simple speak and spell clone. When I got it the voice was sort of jangled, and it still is. It has a pitch knob, which will pitch the thing both up and down, depend on the direction in which you turn it. I installed a 1/4" output jack for your amplifying, or recording pleasure. This thing-a-ma-jig will take 2 AA batteries, and there is no battery compartment cover.
I do some bending. I ought to post all my projects here, and so far the only one I've left out is number one. I am not against custom orders, in fact I'm for it, so if you want to send me your keyboard or toy, and have me bend it, give it a go. If anybody ever needs anything at all, I'll be happy to help you out: preposterousman at gmail.com
