This might not be the best way, please tell me if you have a better idea. I want to build 24 different oscillators one at each musical note ranging from 440 hz to 1661 hz ( 2 octaves ). My idea is to grab a 20k crystal oscillator and divide that to numbers close to the notes. Ex, 20k / 45 = 444.44 then tune that by a variable resistor or capacitor to reach the required frequency. I am ok with digital implementation, if all 24 oscillators can be on at the same time. I do not care what shape or form or amplitude the waves are at other than 50% duty cycles if it is a square, since all of that is going to be thrown at a PLL. please try your best to not make it drift by much. My timeline is 10 days from today. Please use realistic numbers for capacitors and such. One working circuit diagram for one of the oscillators is more than enough, if provided with good explanation.
Hi!
I am an Electronics an Telecommunications Engineer with considerable experience in digital electronics. I think I can finish the task within the deadline and I would love to talk to you regarding the project. I can execute a much simpler digital implementation of the idea. The difference is that the source (free running) frequency and the divided frequencies will all be square waves. We could create sine waves from the free running oscillator but it is simple and can be easily done if we can solve the heart of the problem (the frequency division). However, I would like to understand the problem statement better to tune it to your requirements. I believe I am able to do justice to this task and I would love to have an opportunity to talk with you about this project!
Sincerely,
A.

I have read your project description.
I understand what you want.
I am a MEP ( mechanical, Electrical engineering and plumbing).
you are at right place.
Hello, electronic implementation of this project is quite easy. I will be generating all of the 24 different frequencies and apply superposition before outputting. This way you might turn on and off arbitrary number of frequencies. Analog implementation would be rather difficult online.
I have a diverse experience when it comes to electronic circuit design, as i have a profound engineering background. Kindly review my PORTFOLIO, i can get the job done thanks!
Hi, there are different ways and methods to do your purpose that can be chosen according to time, price and accuracy. I did other projects that similar purpose was done in a part of them.
Hi! I am an Electrical Engineer with the experience of working on several projects like this over the last 5 years. I believe that this should not be a very difficult problem but I would need a more accurate description of your requirement if you want the solution which is best suited for your needs.
I can give you the circuit in 3 days but I mention 7 days as a worst case situation.
I understand if you feel a bit skeptical about assigning the project to a stranger on the internet so if you want to know more about me and also discuss this project in detail before you assign me the project then feel free to drop me a message or email me at bparth.94 (at) gmai (dot) com
About me:
I have a master's degree in Electrical and Computer Engineering from Cornell University with 3 years of experience working as a freelancer and one and a half years working in the industry. I have worked on many circuit design and software design projects so I can provide you with the solution that best for your needs.
