Korg - Nu:Tekt NTS-1 Digital Synth Kit

Product Information

Previously, we received a value from the knob, and if that value multiplied by 64 exceeded the “count”, it would be reset to zero. Korg may on occasions supply software programs, data files and/or documentation belonging to a third party or parties (hereinafter collectively referred to as “Third Party Software”). Makefile”, “manifest.json” and “project.mk” are definition files. The files you’ll need to rewrite according to the effects you will create are “manifest.json” and “project.mk”. This is an “optional” component, and not everyone needs it. Think of this as the command-line variant of “Sound Librarian,” which we described last time. Note that there is a Windows and macOS version of Sound Librarian, but not a Linux version.

The reverbs prove especially suited to leads and atmospheric drones. Hall and plate are impressive staples but the special effects reverbs Space, Riser and Submarine lift this synth to another level, especially for its price. By adding pitch-shifting to the reverb tail – both upwards and down – these add a warped polish to sounds that might otherwise be a bit anaemic. This puts all of the input into the buffer we’ve prepared. This is the “for” statement we used for looping last time, and the “if” statement that makes conditional decisions. “frames” is the number of frames for one channel, so we are setting this value to twice that amount for two channels (LR). What’s confusing is the “++” that comes after the “z”. “z” increases after the “zth” input to the buffer.There are six filters: 2-pole and 4-pole variants for low-pass, band-pass and high-pass. There are sweep rate and depth parameters for adding movement to these too but, again, the functions are buried beneath clunky button-press sequences. For that reason, if you’re planning to develop on Linux, you’ll need to install this tool. Once you’ve successfully installed these tools, let’s build (create the program for) the sample components included with the SDK. Further, as audio programming pros we’re so excited about how the NTS-1 has an audio input and can be used as a synthesizer or as an effects unit. It’s really interesting how the NTS-1 offers all this, while still being eminently affordable. That’s why we proposed this article series—we wanted to tell as many people as possible about the fascination of this product.

The license created by this agreement is personal to you and you may not assign or otherwise transfer your rights or obligations under this agreement without the prior written consent of Korg. The above is the format used for functions. The “value returned” means what kind of data is used to get the results of the process executed by the function, and the “argument” is the data and its type that are given to the function when it is called. By converting to integer, for instance we can change the value of “7.4” in “p” to “7”, dropping the decimal and then storing that in “prev”. Make does not need any additional special installation on macOS, Linux and Windows (and MSYS2), but we will explain where it is otherwise necessary to install.The “p” variable type is “float”, so we get non-rounded numbers like 1.2 and 5.4. When it comes to arrays, there isn’t such a thing as “location 1.2”. That’s why we assume that for the value in location “1.2”, the value is 20% closer to the first value. You might be thinking, “why don’t the numbers start with 1?”. In that case, the loop would end once the number reaches the same number as “frames”. That said, there’s only one chance for the numbers to be the same... so if you make a mistake in your programming and go over the number, you’ll end up with an endless loop. If this happens, the program may freeze, or perhaps the following process will start at zero, which could be convenient... That ties neatly in with the next topic. So, where does this go? On the third line, of course that’s the next array after the “pth”. We put that into “next”. Korg warrants that the Licensed Program when properly used will provide the facilities and functions as described in the accompanying documentation but does not warrant that the operation of the Licensed Program will be uninterrupted or error-free. As you can see in the Readme file, all you need to do to install is to run the prepared shell script.

On the second line, the number subtracted from the “prev” that was converted to an integer from the original “p” is stored in “slope”. A buffer is a place where data for temporary processing is stored or kept. This time, we’ll use the buffer for the array we created last time. We want to store a lot of sound data in this buffer, so we need to make a large array. void DELFX_INIT(uint32_t platform, uint32_t api) { buf_clr_f32(s_delay_ram, BUFFER_LEN); z = 0; z2 = 0; prev = 0; next = 0; p = 0.f; slope = 0.f; isStop = 0; } Last time we talked about the effects we actually made for the NTS-1. Have you tried them out yet? This time, I’ll explain the environment you’ll need to create your own original effects (and oscillators) for the NTS-1.

Effective immediately

Now we move on to the main processing. We’ll first skip to explain the function at the very bottom. a) to Korg at its own expense using all reasonable endeavours to rectify any non-conformance with the warranty by repair (by way of a patch, work around, correction or otherwise) within a reasonable period of time or, For example, if you have the same synthesizer sound in both the left and right channels, but then add the mic sound to just one channel, you’re able to extract the audio from the mic by using the differential from both signals. Does this line of reasoning make sense? Out-of-the-box the oscillator can generate virtual analogue Sawtooth, Triangle and Square waves and VPM waveforms. Variable Phase Modulation (VPM) is Korg's take on FM synthesis found originally in the Prophecy and Z1. In the Prologue the VPM oscillator has 16 types whereas here we appear to have the one carrier/modulator algorithm. It starts with a really throaty sound and then clangs its way to crisper tones as you dial in the overtones. And then there's the last oscillator type which is the Custom/User Multi-Engine Oscillator/Effect engine widget, which we'll come to later. To develop programs, you need a “compiler,” which is a software that converts programs written by humans into machine language that’s readable by a computer. With the logue SDK, we’ll use the “GNU Compiler Collection” (GCC for short).

void MODFX_INIT(uint32_t platform, uint32_t api) { lastSampleL = 0.f; lastSampleR = 0.f; count = 0; }

Key features

We’ll be making another effect this time, so as the designer of the DSP I’ll be in charge of this part. A vocoder uses the audio from a mic input (the “modulator”) to process the sound of a synthesizer (the “carrier”). Although both of these elements require separate inputs, the NTS-1 does not have this feature. So, when the conditions of the “else” statement are met, the knob is being turned, so the stop effect is processed. s1” is the first sound of between the two points previously mentioned, and “s2” is the L and R we’ve prepared, meaning the last sound. If the input volume is still too low, we can overcome this by setting the vocoder parameter A to “Gain” and adjusting this knob to amplify the volume by 100 times maximum.
