Sample Player for Daisy Patch

erwincoumans · September 29, 2020, 6:05pm

Here is an early release of a simple WAV sample player for Daisy Patch:

stereo samples (int/float) from SD card
supports 8/16/24/32bit int and 32/64 bit float samples
press/select sample using encoder
loads samples to memory, up to 4 samples and 48MB total
adjust playback speed from -200% to 200% using CV CTRL1

Cool. Thanks!!! will test it on the weekend

erwincoumans · September 30, 2020, 3:34pm

Sure. It is a first version, at the moment it loads 4 wav files. With a few lines change that allows scrolling up/down, it can load any number of wav files, up to 64MB memory.

Also, it will be straighforward to turn this into a granular synth, that’s up next.

@erwincoumans looks as if there’s a header file missing:

ex_sampleplayer.cpp:4:10: fatal error: util/wav_format.h: No such file or directory
4 | #include “util/wav_format.h”

You have to clone the repository fully, and a git submodule update --init --recursive
I added a new DaisyCloudSeedSourceWithExternals.zip, get that instead of the default github source archives.

Great. That works now. Thanks @erwincoumans!

A new version is available. It can load up to 64 samples, 64MB,
CTRL1 = speed control, CTRL 2 = volume control
at the end of a sample, GATE OUT is triggered.
You can connect GATE OUT to GATE 1 IN to loop a sample
It has a small help menu at start up.

Thank you! You’re a straight G money ganstarr. For the couple projects I’ve found for this, the examples, and the 2 band saturator I just made in Max/Gen~, the Daisy Patch has already become more than worth it’s price.

It’s such a great little multi function module. I hope many decide to use this guy. Hell, I would pay $10-$20 here or there just for really well developed piece of software.

Maybe you’ve found these before, but I figured I would share since you seem way more capable than me to do cool things with them: MaxPatches/stkr.waveshaping.genexpr at master · meta-meta/MaxPatches · GitHub

They’re written in genExpr, so maybe not super valuable, but idk maybe they work well in any code… not sure.

sadly since they updated the SD library this no longer works. I have been attempting to change it based on what I have seen in the one SD card example in the Seed folder but so far i have not had any luck.

Did you eventually find a fix for the SD card issue?

darve · January 14, 2024, 1:09pm

Hey - did anyone figure out the above?

jurrebakker · May 15, 2024, 3:09pm

Hey,

I have a question. I recently bought a POD and I was wondering if I can use an external mic for the input and record a sound to the microSD card. Also that there is an option to use it for playback. For example. Use one button from the Pod to activate the recording function from the external mic. And the other button for playback. I think this is complicated to achieve but I hope there is something possible like this.

Please let me know.

Thank you

@cricketbee
I updated the app to use the latest Daisy SDK back in October 2022, so it should work again:GitHub - erwincoumans/DaisyCloudSeed
@jurrebakker If you can do a bit of C++ you could add this indeed, I haven’t gotten back to this project for a while (it was mostly a COVID project).

jurrebakker · May 15, 2024, 6:54pm

Thank you for the reply. Unfortunately I don’t have experience with C++. I recently started with Pure Data. Would it be possible to integrate this tool within Pure Data or Gen~ in MaxMsp?

Thank you.

@erwincoumans Hi I’m looking at this sample player for reference for my own design and I’m a bit confused as to whether your program reads from the SD card to SDRAM or does it stream straight from the SD card? If it were the latter case (which the code points to), why is the current limit of samples on SD card 64MB (i.e. the total amount of SDRAM - seemingly pointing to you loading all the SD card files straight to SDRAM instead of streaming from card)?

erwincoumans · October 28, 2024, 7:53pm

@wailem
The Sample Player first lists all WAV files on SD card, and once you select one, it read the entire WAV in SDRAM:

github.com

erwincoumans/DaisyCloudSeed/blob/master/patch/SamplePlayer/sample_player_app.cpp#L127


      
          {
            m_file_sizes[m_file_cnt_] = f_size(&SDFile);
            char* memoryBuffer = 0;
            int memorySize= 0;
            UINT size = m_file_sizes[m_file_cnt_];
            size_t bytesread;
            memoryBuffer = (char*) custom_pool_allocate(size);
            if (memoryBuffer)
            {
              UINT bytesRead;
              // Read the whole WAV file
              if(f_read(&SDFile,(void *)memoryBuffer,size,&bytesread) == FR_OK)
              {
                memorySize = size;
                m_dataSources[m_file_cnt_] = MemoryDataSource(memoryBuffer, memorySize);
                m_wavFileReaders[m_file_cnt_].getWavInfo(m_dataSources[m_file_cnt_]);
                
                m_wavFileReaders[m_file_cnt_].resize();
                m_wavTickers[m_file_cnt_] = m_wavFileReaders[m_file_cnt_].createWavTicker(samplerate);
                //start each sound inactive
                m_wavTickers[m_file_cnt_].finished_ = true;
