After various versions I came to the conclusion that your system is the simplest. In this version I used a different method to filter the notes and i increase the song lenght.

True... after some test with a clock where are no way to make a continuous sound, one note have its fixed time of execution. So, is not necessary indixing the notes, just sort notes by time: store only pitch (or more pitch) and time of execution.

To chain more constant combinators and avoid sum of ...

Hi, now i understand your system, is not so simple :mrgreen:
I'm working in this way:

Like you i will use one signal to encode 3 different pitch, 1 time and 1 note position.
One constant combinator can contain 18 signals ...

Wow, nice, to create the music you have used some tools to convert MIDI file to bits or you have done all manualy ?
it is very interesting now to try to optimize, reduce the bits and use more speakers... i will try

Hi, personaly i'm using this Logic for labs to not waste any unecessary and expensive science pack objects. It's a possible solution for you issue ? ;)
To start process just insert manualy how many item you want on the belt, every time the transport belt at the end read the exit production, send ...

A simplest solution: insert only that inserter read.
To start the process only insert manualy how many items you want in the lab's belt loop, every time inserters put an science pack in the lab, the transport belts ad one more item in the loop. Work well when you are researching a tech that require ...

Hi, I would like to propose you my solution to make a rainbow belt: viewtopic.php?f=193&t=60203 but need to make a modification because the ratio is constant and not depend by actual labs consumption for technology that you are researching.

Waste Recirculations and Raw materials line

The purpose of recycling is to reuse resources that have not been used by furnaces instead using the main line.

Furnaces Group
The first problem of furnace is the steel and brick product that require more than one raw material, before changing product the furnace must be emptied. This is not necessary for iron and copper plates. Two memory cells store the current raw material inside furnace minus the ...

Signal Decoder (2bit)
Each group of furnaces needs to know which object must smelting. Decode the main signal is the easiest part done with a bit mask operation (11b = 3), just provide the current group number (zero base so from 0 for first to N-1 for last).

Signal Encoder (2bit)
Once the number of furnace groups necessary for each product has been obtained, the signal must be distributed to each group. To avoid using one wire for each group I thought to compressing the signals into a single number. This also allows me to greatly simplify the number ...

Product request calculation
The main task is to calculate which products are needed and which priority. The easiest solution is to read how many products are stored in the chests during production, fewer objects there are means more demand.

The first simplest solution is to calculate how many ...

Hi all, this is my first try to make a four mixed product furnace setup.
The goal it's to use only one furnaces factory to satisfy variable request of Brick, Iron Plate, Cooper Plate and Steel:
It's a work in progress, I prefer to explain in detail my proposal by splitting the whole system in ...

Hi, sorry for my english.
I don't know if similar already exists, but I needed to compress the belt's items in many situations.
The operation is simple
