I’m Mizutani from Sleepfreaks. In this video, I will talk about the oscillator section in SERUM. First, you can select various kinds of waveforms from this small window. As we did for the presets, you can change it by clicking these arrows. It sounds quite good. Under the waveform selection window, there is a section for tuning. You can change their pitch in the range of ±4 octaves. In SEM, you can change their pitch in the unit of a semitone, in the range of ±1 octave. In FIN, you can chage their pitch in the unit of 1/100 of a semitone, in the range of ±1 semitone. CRS on the right is quite useful. For example, let’s see how it sounds when we use OCT in case we want to gradually raise the pitch. It went up to +4 oct discretely. Let’s do it with SEM. This also went up to +1 oct discretely. Let’s do it with FIN. It’s smoother, but it only goes up to a semitone above. Let’s try CRS. That was awesome. You can move it up to 6 octaves smoothly. We can use this in the climax of a song. Next, the UNISON parameter is normaly set to 1, but you can change the number of sounds by
dragging it up and down, and you can also change
their tuning by tweaking the DETUNE knob. It sounds wide with detune. You can adjust the volume balance of the side and the center sounds. They are labeled in yellow and green. The range of detune is 2 and a half tone in the default setting. You can see that in the UNISON>RANGE in the GLOBAL tab. The left side is OSC A, and the right side is OSC B. You can increase the range up to 4 octaves. This means if you set the range to 12, which is
an octave, then set UNISON to 3, blend them equally,
and move the DETUNE knob, the sound with different octaves will spread from the center, and it sounds quite interesting. Next, I will change the waveform and explain the PHASE and RAND knob. I will choose Analog>Basic Shapes which stands for sine wave. PHASE determines the timing of the sound emittance,
and RAND determines the time interval of the sound emittance. Let’s play it and see how it sounds. It sounds pretty different. Next, RAND. It changes each time it plays. If you want the articulation the exact same each time, set RAND to 0%, and it’s useful when you use bass. Then you can adjust the timing by tweaking the PHASE knob. Next, the warp knob. This time I will choose Analog>4088. The Warp is normally turned off, but the menu pops up when you click on it, and you can access to Sync, Bend, FM, etc., which dramatically changes your sound. For example, you can tweak this knob to adjust the level of the sync. It became agressive and trebly as I turned it up. When you select FM (from B), the waveform
in OSC B will affect the waveform in OSC A,
so you need to turn OSC B on. It’s ok if the level of B is 0. It became a pretty cool FM sound. Next, let’s have a listen to the main feature, Wave Table Position. This also dramatically changes the sound. You might think it’s the same as the warp knob next to that, but it’s quite different. A 3D diagram shows up when you click on the wave. The yellow line represents the current waveform. Let’s look it more in detail. The editor window shows up when you click on this pen icon. The Wave Table is composed with these waveforms at the bottom. In the default waveform, the nothing will change even if you tweak the WT POS knob. That is because there is only one waveform. Let’s add waveforms and create your own Wave Table. When you click on the + button, the wave labeled in red will be copied to the adjecent box. You can drag and use the tools on the left to edit the waveform in the top window. If you want to edit it in detail, you can make the the grid size smaller by dragging here. It’s pretty easy. Add a wave and edit it. That’s the way to do it. You need to keep in mind that the selected wave in red will be copied to the adjecent box of itself. For example, if you click the plus button
when you select the wave on the very left,
the copy of it will be inserted next to it. If you want to copy the wave that you’ve created, select the wave and click on COPY, and select the box where you want to paste and click on PASTE. This is also easy. Let’s click on the ‘x’ button and end the editor, and move around the the Wave Table. It doesn’t shift smoothly. You need to do a trick to fix it. It’s actually quite easy. Open the editor and use Morph to connect the waves smoothly. There are many kinds of morph, but the one on the top is the recommended default one. Let’s select this and move around the Wave Table again. It shifts smoothly now, and it was easy. Let’s look at the editor window again. We’ve edited the wave in the bottom section, but you can actually edit it in the FFT area in the upper section. Select the wave and click on this arrow, then a number of bars show up. It might seem quite complicated but it’s actually quite easy. Right click and click on ‘Clear all’, all the waves will be gone. Drag here on the left to the top. It’a sine wave. The one on the left is the fundamental pitch, and the others on the right are the harmonics. The bars at the bottom controls the phase of the harmonics. Nothing happens even if you move the phase where there is no bar on the top. In the FFT Area, you only need to drag, so you can make it intuitively. Finally, you can use your own audio source as a oscillator. Let’s put in this drum loop just by drag and dropping. Normally, when we do this kind of thing, it often mostly keeps the original sound, but in case of SERUM, it analyzes the sound source
and put in the Wave Table, so some sample
might not retain the original sound. When you bring an audio file in the wave form window, you can see there are 4 imports and 3 FFTs. The first one is for the simple sound,
next is for the complicated ones, and the one
at the bottom is for one shot synths. The FFTs are for the sound without pitch, such as drums and speechs. If you feel that the selection is difficult, the third one from the top is recommended to use. But it doesn’t mean that you will be arrested if you don’t do it, so it might be interesting to try all of them at once. This time let’s load it in FFT 2048. You can see that a new Wave Table showed up. Let’s use Morph in the editor window to make it smooth. Let’s see how it sounds. It’s quite cool. It doesn’t retain the original sound. Let’s increase the number of unison, and apply detune. Turn Warp into Sync, apply ENV2 to WT POS and SYNC, and make the attack slower. Finally, apply chorus, delay, and reverb in the FX section. A very interesting pad sound has been created. SERUM is cool and very fun to play. It’s too fun to sleep. I will end this video here, and in the next video, I will talk about LFO, modulation, and matrix. Thanks for watching!
